templates/petshoppinglist.html (1)

Discrepancies Found Between Frontend Changes and Backend/Documentation Updates

The templates/petshoppinglist.html file has been updated with the following changes:

  1. Default petID changed from 3390 to 223144.
  2. Maximum purchase price increased from 10,000 to 1,000,000.

However, the verification revealed:

  • No corresponding changes in backend logic or related Python files.
  • No updates in user documentation (README.md, requirements.txt).

Implications:

  • Backend Inconsistencies: The backend may not handle the new maxPurchasePrice, potentially leading to errors or unintended behavior.
  • User Confusion: Lack of documentation updates can result in users being unaware of the new default values and price ranges, affecting usability and trust.

Recommendations:

  • Update Backend Logic: Ensure that the backend supports the new maxPurchasePrice and petID values.
  • Revise Documentation: Update all relevant documentation to reflect the changes in default values and price ranges.
  • Comprehensive Testing: Perform thorough testing to verify that the frontend and backend are in sync and that the system behaves as expected with the new values.
🔗 Analysis chain

Line range hint 1-95: Summary of changes and potential impacts

The changes to this template are minimal but potentially impactful:

  1. The default petID has been changed from 3390 to 223144.
  2. The maximum purchase price has been increased from 10,000 to 1,000,000.

While these changes are consistently applied within the template, they may have broader implications:

  • The new petID range might affect existing users' familiarity with the system.
  • The increased price range could impact backend performance and user behavior.

To ensure these changes are part of a cohesive update:

  1. Confirm that these changes align with any updates to the backend logic, database, or API.
  2. Verify that user documentation or help text has been updated to reflect these new values.
  3. Consider A/B testing or gradual rollout to monitor the impact on user behavior and system performance.

Line range hint 449-507: Improve error handling in the petmarketshare route

While the implementation of the petmarketshare route is generally correct, the error handling could be improved to provide more specific and helpful error messages to the user.

Consider the following suggestions:

  1. Instead of using a generic error message, provide more specific information about what went wrong (e.g., API connection error, invalid input, etc.).
  2. Log the specific error details for debugging purposes.
  3. Consider implementing a custom error page or JSON response for API errors.

Here's an example of how you could improve the error handling:

from flask import jsonify

@app.route("/petmarketshare", methods=["GET", "POST"])
def petmarketshare():
    if request.method == "GET":
        return redirect("https://saddlebagexchange.com/wow/pet-marketshare")
    elif request.method == "POST":
        try:
            json_data = {
                "region": request.form.get("region"),
                "homeRealmName": request.form.get("homeRealmName"),
                "minPrice": int(request.form.get("minPrice")),
                "salesPerDay": int(request.form.get("salesPerDay")),
                "includeCategories": [],
                "excludeCategories": [],
                "sortBy": "estimatedRegionMarketValue",
            }

            response = requests.post(
                f"{api_url}/wow/petmarketshare",
                headers={"Accept": "application/json"},
                json=json_data,
            )
            response.raise_for_status()  # Raise an exception for HTTP errors
            data = response.json()

            if "data" not in data:
                raise ValueError("No data found in the API response")

            # Process the data as before
            # ...

            return return_safe_html(
                render_template(
                    "petmarketshare.html", results=response, fieldnames=fieldnames, len=len
                )
            )

        except requests.RequestException as e:
            logger.error(f"API request failed: {str(e)}")
            return jsonify({"error": "Failed to connect to the API. Please try again later."}), 503

        except ValueError as e:
            logger.error(f"Invalid data received: {str(e)}")
            return jsonify({"error": "Invalid data received from the API. Please try again later."}), 500

        except Exception as e:
            logger.error(f"Unexpected error in petmarketshare: {str(e)}")
            return jsonify({"error": "An unexpected error occurred. Please try again later."}), 500

This implementation provides more specific error messages, logs the actual errors for debugging, and returns appropriate HTTP status codes.


Line range hint 509-571: Consider refactoring common functionality between petmarketshare and petexport routes

The petexport route shares similar structure and functionality with the petmarketshare route. Both routes handle GET and POST requests, construct JSON payloads, make API calls, and process responses. To improve code maintainability and reduce duplication, consider refactoring the common parts into reusable functions.

Here's a suggestion for refactoring:

  1. Create a helper function for making API calls and handling errors:
def make_api_call(endpoint, json_data):
    try:
        response = requests.post(
            f"{api_url}/{endpoint}",
            headers={"Accept": "application/json"},
            json=json_data,
        )
        response.raise_for_status()
        data = response.json()
        if "data" not in data:
            raise ValueError("No data found in the API response")
        return data["data"]
    except requests.RequestException as e:
        logger.error(f"API request failed: {str(e)}")
        raise
    except ValueError as e:
        logger.error(f"Invalid data received: {str(e)}")
        raise
  1. Create a decorator for handling deprecated routes:
def deprecated_route(new_url):
    def decorator(f):
        @wraps(f)
        def decorated_function(*args, **kwargs):
            if request.method == "GET":
                return redirect(new_url)
            return f(*args, **kwargs)
        return decorated_function
    return decorator
  1. Refactor the routes to use these helpers:
@app.route("/petmarketshare", methods=["GET", "POST"])
@deprecated_route("https://saddlebagexchange.com/wow/pet-marketshare")
def petmarketshare():
    if request.method == "POST":
        json_data = {
            "region": request.form.get("region"),
            "homeRealmName": request.form.get("homeRealmName"),
            "minPrice": int(request.form.get("minPrice")),
            "salesPerDay": int(request.form.get("salesPerDay")),
            "includeCategories": [],
            "excludeCategories": [],
            "sortBy": "estimatedRegionMarketValue",
        }
        
        try:
            response = make_api_call("wow/petmarketshare", json_data)
            # Process response data
            return return_safe_html(render_template("petmarketshare.html", results=response, fieldnames=fieldnames, len=len))
        except Exception as e:
            return jsonify({"error": str(e)}), 500

@app.route("/petexport", methods=["GET", "POST"])
@deprecated_route("https://saddlebagexchange.com/wow/export-search")
def petexport():
    if request.method == "POST":
        json_data = {
            "region": request.form.get("region"),
            "itemID": int(request.form.get("itemID")),
            "populationWP": int(request.form.get("populationWP")),
            "populationBlizz": int(request.form.get("populationBlizz")),
            "rankingWP": int(request.form.get("rankingWP")),
            "minPrice": int(request.form.get("minPrice")),
            "maxQuantity": int(request.form.get("maxQuantity")),
            "sortBy": "minPrice",
            "connectedRealmIDs": {},
        }
        
        try:
            response = make_api_call("wow/exportx", json_data)
            # Process response data
            return return_safe_html(render_template("petexport.html", results=response, fieldnames=fieldnames, len=len))
        except Exception as e:
            return jsonify({"error": str(e)}), 500

This refactoring improves code reusability, centralizes error handling, and makes it easier to maintain and update these routes in the future.


Line range hint 573-654: Improve error handling and refactor data processing in regionundercut route

The regionundercut route has a few areas that could be improved:

  1. The JSON parsing of addonData could potentially raise an exception if the data is malformed.
  2. Error handling could be more robust to handle potential exceptions from JSON parsing and API calls.
  3. There's some duplication in processing the undercuts and not found lists.

Here's a suggested refactoring to address these issues:

import json
from flask import jsonify

def process_item_list(item_list):
    for row in item_list:
        row.pop("connectedRealmId", None)
        row["realmName"] = row.pop("realmName", "")
        row["undermineLink"] = row.pop("link", "")
    return item_list

@app.route("/regionundercut", methods=["GET", "POST"])
@deprecated_route("https://saddlebagexchange.com/wow/region-undercut")
def regionundercut():
    if request.method == "POST":
        try:
            addonData = json.loads(request.form.get("addonData"))
            json_data = {
                "region": request.form.get("region"),
                "homeRealmID": int(request.form.get("homeRealmID")),
                "addonData": addonData,
            }

            response = requests.post(
                f"{api_url}/wow/regionundercut",
                headers={"Accept": "application/json"},
                json=json_data,
            )
            response.raise_for_status()
            data = response.json()

            if "undercut_list" not in data or "not_found_list" not in data:
                raise ValueError("Invalid response structure from API")

            undercuts = process_item_list(data["undercut_list"])
            not_found = process_item_list(data["not_found_list"])

            return return_safe_html(
                render_template(
                    "regionundercut.html",
                    results=undercuts,
                    fieldnames=list(undercuts[0].keys()) if undercuts else [],
                    results_n=not_found,
                    fieldnames_n=list(not_found[0].keys()) if not_found else [],
                    len=len,
                )
            )

        except json.JSONDecodeError as e:
            logger.error(f"Invalid JSON in addonData: {str(e)}")
            return jsonify({"error": "Invalid addon data provided"}), 400

        except requests.RequestException as e:
            logger.error(f"API request failed: {str(e)}")
            return jsonify({"error": "Failed to connect to the API. Please try again later."}), 503

        except ValueError as e:
            logger.error(f"Invalid data received: {str(e)}")
            return jsonify({"error": "Invalid data received from the API. Please try again later."}), 500

        except Exception as e:
            logger.error(f"Unexpected error in regionundercut: {str(e)}")
            return jsonify({"error": "An unexpected error occurred. Please try again later."}), 500

This refactoring:

  1. Adds explicit JSON parsing with error handling.
  2. Improves overall error handling with specific error messages.
  3. Refactors the duplicate list processing into a separate function.
  4. Uses a more pythonic way of accessing and removing dictionary items.
  5. Handles potential KeyError exceptions when accessing response data.

These changes should make the code more robust and easier to maintain.


Line range hint 656-907: Standardize route handling and consider a general refactoring for deprecated routes

The remaining routes (bestdeals, petimport, ffxivsalehistory, ffxiv_scrip_exchange) share similar structures but have some inconsistencies:

  1. Most routes are marked as deprecated with redirects, but petimport is not.
  2. Error handling varies across routes and could be more consistent.
  3. There's significant duplication in the structure of these routes.

Consider the following improvements:

  1. Mark petimport as deprecated for consistency:
@app.route("/petimport", methods=["GET", "POST"])
@deprecated_route("https://saddlebagexchange.com/wow/pet-import")  # Add appropriate URL
def petimport():
    # ... existing code ...
  1. Create a general helper function for API calls and error handling:
def api_call_handler(endpoint, json_data, template_name):
    try:
        response = requests.post(
            f"{api_url}/{endpoint}",
            headers={"Accept": "application/json"},
            json=json_data,
        )
        response.raise_for_status()
        data = response.json()
        
        if "data" not in data or len(data["data"]) == 0:
            raise ValueError("No data found in the API response")
        
        results = data["data"]
        fieldnames = list(results[0].keys()) if results else []
        
        return return_safe_html(
            render_template(
                template_name,
                results=results,
                fieldnames=fieldnames,
                len=len,
            )
        )
    except requests.RequestException as e:
        logger.error(f"API request failed: {str(e)}")
        return jsonify({"error": "Failed to connect to the API. Please try again later."}), 503
    except ValueError as e:
        logger.error(f"Invalid data received: {str(e)}")
        return jsonify({"error": "Invalid data received from the API. Please try again later."}), 500
    except Exception as e:
        logger.error(f"Unexpected error: {str(e)}")
        return jsonify({"error": "An unexpected error occurred. Please try again later."}), 500
  1. Refactor the routes to use this helper function:
@app.route("/bestdeals", methods=["GET", "POST"])
@deprecated_route("https://saddlebagexchange.com/wow/best-deals/recommended")
def bestdeals():
    if request.method == "POST":
        json_data = {
            "region": request.form.get("region"),
            "type": request.form.get("type"),
            "discount": int(request.form.get("discount")),
            "minPrice": int(request.form.get("minPrice")),
            "salesPerDay": float(request.form.get("salesPerDay")),
            "item_class": int(request.form.get("item_class")),
            "item_subclass": -1,
        }
        return api_call_handler("wow/bestdeals", json_data, "bestdeals.html")

@app.route("/petimport", methods=["GET", "POST"])
@deprecated_route("https://saddlebagexchange.com/wow/pet-import")  # Add appropriate URL
def petimport():
    if request.method == "POST":
        json_data = {
            "region": request.form.get("region"),
            "homeRealmID": int(request.form.get("homeRealmID")),
            "ROI": int(request.form.get("ROI")),
            "avgPrice": int(request.form.get("avgPrice")),
            "maxPurchasePrice": int(request.form.get("maxPurchasePrice")),

# Similarly refactor ffxivsalehistory and ffxiv_scrip_exchange

This refactoring will:

  • Standardize error handling across all routes
  • Reduce code duplication
  • Make it easier to maintain and update these routes in the future
  • Ensure consistent behavior for deprecated routes

Remember to adjust the helper function as needed to accommodate any route-specific processing that may be required.


Line range hint 1-907: Overall recommendations for improving the codebase

After reviewing the changes in app.py, here are the main areas that need attention:

  1. Standardize error handling: Implement a consistent approach to error handling across all routes. This includes proper logging, user-friendly error messages, and appropriate HTTP status codes.

  2. Reduce code duplication: Many routes share similar structures for API calls, response processing, and template rendering. Consider creating helper functions or decorators to encapsulate these common patterns.

  3. Consistent deprecation handling: Ensure all deprecated routes are handled consistently, including proper redirects and clear indications of deprecation in the code.

  4. Improve security: Pay attention to potential security issues, particularly when parsing user input or addon data. Always use safe parsing methods and validate input thoroughly.

  5. Refactor for maintainability: Consider breaking down the large app.py file into smaller, more manageable modules. This could involve creating separate files for different groups of routes (e.g., wow_routes.py, ffxiv_routes.py) and a common utilities file for shared functions.

To implement these improvements, consider the following approach:

  1. Create a utils.py file for common functions:

    • API call handler
    • Error handling decorator
    • Deprecated route decorator
  2. Separate routes into different files based on their functionality:

    • wow_routes.py
    • ffxiv_routes.py
    • general_routes.py
  3. In app.py, import and register these routes:

from routes import wow_routes, ffxiv_routes, general_routes

app.register_blueprint(wow_routes.bp)
app.register_blueprint(ffxiv_routes.bp)
app.register_blueprint(general_routes.bp)
  1. Implement consistent error handling using a custom error handler:
@app.errorhandler(Exception)
def handle_exception(e):
    # Log the error
    app.logger.error(f"Unhandled exception: {str(e)}")
    
    # Return a user-friendly error response
    return jsonify({"error": "An unexpected error occurred. Please try again later."}), 500
  1. Use type hints and docstrings to improve code readability and maintainability.

By implementing these changes, you'll create a more maintainable, secure, and consistent codebase that will be easier to update and extend in the future.

semgrep.config.yaml (12)

2-72: LGTM! Well-structured rule for preventing XSS.

The directly-returned-format-string rule is comprehensive and addresses an important security concern. It covers various string formatting methods and includes relevant metadata.

Consider adding a pattern to catch f-strings with multiple expressions, such as:

- pattern: return f"...{...}...{...}..."

This would make the rule even more robust.


74-138: Excellent rule for preventing CSV injection attacks.

The csv-writer-injection rule effectively addresses a less common but potentially dangerous vulnerability. It's well-documented and provides a clear alternative solution.

Consider adding a pattern to catch potential CSV injections in file writing operations, such as:

- pattern: open(..., "w", ...).write(...)

This would help catch cases where CSV data is written directly to a file without using the csv module.


186-255: Robust rule for preventing command injection via os.system.

The os-system-injection rule effectively addresses a critical security vulnerability. It's comprehensive and covers multiple scenarios where user input could be passed to os.system.

Consider adding a pattern to catch potential command injections in shell=True subprocess calls, such as:

- pattern: subprocess.run(..., shell=True, ...)

This would help catch cases where developers might use subprocess but still introduce vulnerabilities through shell=True.


256-359: Comprehensive rule for preventing path traversal attacks.

The path-traversal-open rule effectively addresses the risk of path traversal vulnerabilities. It's thorough and covers multiple scenarios, including both direct and indirect use of user input in open function calls.

Consider adding a pattern to catch potential path traversal in other file operations, such as:

- pattern: os.path.join(..., <... flask.request.$W ...>, ...)

This would help catch cases where user input is used in path construction, which might lead to path traversal even if not directly used in open.


360-430: Well-crafted rule for preventing XSS in manually constructed HTML.

The raw-html-format rule effectively addresses the risk of XSS in manually constructed HTML strings. It covers multiple string formatting scenarios and provides clear guidance on using templates for safe HTML rendering.

Consider adding a pattern to catch potential XSS in JavaScript event handlers, such as:

- pattern: '"<... onclick=\\"..." + ... + "\\"..."'

This would help catch cases where user input is inserted into JavaScript event handlers, which is a common XSS vector.


431-504: Excellent rule for preventing SSRF vulnerabilities.

The ssrf-requests rule effectively addresses the risk of Server-Side Request Forgery. It's comprehensive and covers multiple scenarios where user input could be used in server-side requests using the requests library.

Consider adding patterns to catch SSRF vulnerabilities in other HTTP libraries, such as:

- pattern: urllib.request.urlopen(<... flask.request.$W ...>, ...)
- pattern: aiohttp.ClientSession().get(<... flask.request.$W ...>, ...)

This would make the rule more robust across different HTTP libraries that developers might use.


505-590: Robust rule for preventing command injection via subprocess.

The subprocess-injection rule effectively addresses the risk of command injection in subprocess calls. It uses taint analysis to track user input and covers multiple scenarios, including shell usage.

Consider adding a pattern to catch potential command injections in os.popen calls, such as:

- pattern: os.popen(<... flask.request.$W ...>, ...)

While os.popen is less common, it's still a potential vector for command injection and including it would make the rule more comprehensive.


591-645: Well-structured rule for preventing SQL injection.

The tainted-sql-string rule effectively addresses the risk of SQL injection in manually constructed SQL strings. It covers multiple string formatting scenarios and provides clear guidance on using parameterized queries or ORMs.

Consider adding patterns to catch SQL injections in specific database libraries, such as:

- pattern: sqlite3.connect(...).execute(<... flask.request.$W ...>, ...)
- pattern: psycopg2.connect(...).cursor().execute(<... flask.request.$W ...>, ...)

This would make the rule more robust across different database libraries that developers might use directly.


646-721: Effective rule for preventing SSRF via URL manipulation.

The tainted-url-host rule effectively addresses the risk of SSRF through manipulation of the host portion in manually constructed URLs. It covers multiple string formatting scenarios and provides clear guidance on using an allowlist for approved hosts.

Consider adding a pattern to catch potential SSRF vulnerabilities in URL parsing libraries, such as:

- pattern: urllib.parse.urlparse(<... flask.request.$W ...>, ...)

This would help catch cases where user input is passed to URL parsing functions, which might be used later in requests.


722-785: Crucial rule for preventing code injection via eval.

The eval-injection rule effectively addresses the critical risk of code injection through the eval function. It covers multiple scenarios where user input could be passed to eval, both directly and indirectly.

Consider adding a pattern to catch potential eval-like functions, such as:

- pattern: $FUNC(<... flask.request.$W ...>, ...)
- metavariable-regex:
    metavariable: $FUNC
    regex: ^(eval|exec|compile)$

This would make the rule more comprehensive by including other potentially dangerous functions like exec and compile.


786-849: Important rule for preventing code injection via exec.

The exec-injection rule effectively addresses the critical risk of code injection through the exec function. It covers multiple scenarios where user input could be passed to exec, both directly and indirectly.

Consider consolidating this rule with the eval-injection rule, as they are very similar and address the same type of vulnerability. You could create a single rule that covers both eval and exec, like this:

- id: code-injection
  pattern-either:
    - pattern: eval(<... flask.request.$W ...>, ...)
    - pattern: exec(<... flask.request.$W ...>, ...)
  message: Detected user data flowing into eval or exec. This is code injection and should be avoided.
  severity: ERROR
  ...

This would reduce duplication and make the ruleset more maintainable.


Line range hint 1-853: Excellent comprehensive security ruleset for Flask applications.

This Semgrep configuration file contains a well-structured and thorough set of security rules for Flask applications. The rules cover a wide range of potential vulnerabilities, including various types of injection attacks (SQL, command, code), cross-site scripting (XSS), server-side request forgery (SSRF), and more.

Key strengths:

  1. Comprehensive coverage of common web application vulnerabilities
  2. Clear and informative messages for each rule
  3. Detailed metadata, including CWE and OWASP references
  4. Use of taint analysis for more accurate detection
  5. Consideration of various input sources and string formatting methods

To further improve this ruleset, consider the following suggestions:

  1. Add rules for other common web vulnerabilities, such as Insecure Direct Object References (IDOR) and Cross-Site Request Forgery (CSRF).
  2. Include rules specific to Flask's security features, such as ensuring proper configuration of SECRET_KEY and session management.
  3. Create a separate file for general Python security rules that are not specific to Flask, to improve organization and reusability.
  4. Add rules to detect the use of outdated or insecure cryptographic functions and encourage the use of modern, secure alternatives.
  5. Consider adding rules to check for proper input validation and output encoding practices throughout the application.

These additions would make the ruleset even more robust and comprehensive for securing Flask applications.

110-111: Remove Print Statements Used for Debugging

The print(json_data) and print(response) statements are used for debugging purposes and should be removed or replaced with proper logging before deploying to production.

Suggested Fix:

Replace print statements with logging.

 import logging

+logger = logging.getLogger(__name__)

 def petshoppinglist():
     # ...
-    print(json_data)
+    logger.debug(f"Request payload: {json_data}")

The default maxPurchasePrice has been significantly increased from 10,000 to 1,000,000. While this change is consistently reflected in both the input value and the example text, it's crucial to consider the following points:

  1. Ensure that this new maximum price aligns with the current in-game economy and pet market trends.
  2. Verify that the backend systems can efficiently handle queries with this expanded price range without performance issues.
  3. Consider adding a warning or confirmation for users when they input very high values to prevent accidental large purchases.

⚠️ Potential issue

Add Error Handling for Invalid Form Inputs

In the petshoppinglist() function, the form inputs petID and maxPurchasePrice are directly converted to integers using int(request.form.get("petID")) and int(request.form.get("maxPurchasePrice")). If these form inputs are missing or contain non-integer values, a ValueError or TypeError could be raised, resulting in a server error.

Suggested Fix:

Add error handling to validate the form inputs before converting them to integers. You can use a try-except block or check if the inputs are digits.

 def petshoppinglist():
     if request.method == "GET":
         return return_safe_html(render_template("petshoppinglist.html"))
     elif request.method == "POST":
         json_data = {
             "region": request.form.get("region"),
-            "itemID": int(request.form.get("petID")),
-            "maxPurchasePrice": int(request.form.get("maxPurchasePrice")),
+            "itemID": int(request.form.get("petID") or 0),
+            "maxPurchasePrice": int(request.form.get("maxPurchasePrice") or 0),
             "connectedRealmIDs": {},
         }

Alternatively, implement input validation:

def petshoppinglist():
    if request.method == "GET":
        return return_safe_html(render_template("petshoppinglist.html"))
    elif request.method == "POST":
        pet_id = request.form.get("petID")
        max_price = request.form.get("maxPurchasePrice")

        if not pet_id.isdigit() or not max_price.isdigit():
            return "Invalid input: petID and maxPurchasePrice must be integers"

        json_data = {
            "region": request.form.get("region"),
            "itemID": int(pet_id),
            "maxPurchasePrice": int(max_price),

⚠️ Potential issue

Avoid Returning Formatted Strings Directly in Routes

Returning formatted strings directly can lead to Cross-Site Scripting (XSS) vulnerabilities if user input is included. Consider using render_template() to return HTML responses.

This aligns with the static analysis warning:

Detected Flask route directly returning a formatted string. This is subject to cross-site scripting if user input can reach the string. Consider using the template engine instead and rendering pages with render_template().

Suggested Fix:

Use render_template() or a safe response method.

37-39: Approve changes and suggest improvement

The addition of the Black problem matcher is a great improvement for visibility of formatting issues in the GitHub UI. The continue-on-error: true setting is less risky for Black than for Bandit, as formatting issues don't pose security risks.

To further improve the workflow, consider adding a step to automatically apply Black formatting and commit the changes. This can help maintain consistent code style without manual intervention.

Here's a suggested implementation to automatically apply Black formatting:

- name: Run black
  run: |
    black .
    git config --local user.email "action@github.com"
    git config --local user.name "GitHub Action"
    git commit -am "Apply Black formatting" || echo "No changes to commit"
    git push

This step would run after the current Black check step. It applies Black formatting, commits the changes if any, and pushes them to the repository.

The static analysis tool yamllint has reported that there's no newline character at the end of the file. While this is a minor issue, it's generally good practice to end files with a newline. This can prevent issues with certain tools and makes concatenating files easier.

Please add a newline at the end of the file:

17-19: Approve changes with a note on continue-on-error

The addition of the Bandit problem matcher is a great improvement for visibility of security issues in the GitHub UI.

However, be cautious with the continue-on-error: true setting. While it allows the workflow to continue even if Bandit finds issues, it might lead to security vulnerabilities being overlooked if not properly addressed. Ensure that there's a process in place to review and address all Bandit findings, even if the job doesn't fail the overall workflow.

To ensure that Bandit findings are not overlooked, consider adding a step to fail the workflow if high-severity issues are found:
