20-28: Consider improving error message formattingThe error message handling looks good, but consider using GitHub's workflow commands for better visibility:
- echo "::error::Black found code style issues. See the diff below:" + echo "::error title=Black Format Check::Found code style issues. See the diff below for details:"
Line range hint
10-31: Security concern: Bandit security scanner has been removedThe removal of the Bandit security scanner job reduces the security coverage of the codebase. While the Black formatter improvements are good, we should maintain security scanning capabilities.
Consider either:
- Reinstating the Bandit job
- Replacing it with an alternative security scanner
- Confirming if security scanning has been moved to a separate workflow
Would you like me to help draft a configuration for either option?
templates/petshoppinglist.html (3)
41-44: Consider adding input validation constraintsThe petID input field accepts any number. Consider adding min/max constraints to prevent invalid inputs:
- <input name="petID" type="number" class="form-control" value="223144"> + <input name="petID" type="number" class="form-control" value="223144" min="1" max="999999">
51-52: Add thousand separators for better readabilityLarge numbers like 1000000 are hard to read. Consider adding thousand separators in the example text:
- <div class="form-text">maxPurchasePrice. Pick the most amount of gold you want to spend. ex: <span style="color: #d97e84;">1000000</span></div> + <div class="form-text">maxPurchasePrice. Pick the most amount of gold you want to spend. ex: <span style="color: #d97e84;">1,000,000</span></div>
Line range hint
35-65: Security: Add rel="noopener" to target="_blank" linksUsing target="_blank" without rel="noopener" can expose security vulnerabilities. Also, the form action points to a deprecated route.
- <a href="/itemnames" target="_blank"> + <a href="/itemnames" target="_blank" rel="noopener"> - <form method="POST" action="/petshoppinglist" target="_blank" class="scanform"> + <form method="POST" action="/wow/shopping-list" target="_blank" rel="noopener" class="scanform">routes/wow.py (1)
131-139: Move column configuration to constantsHard-coded column names should be moved to module-level constants for better maintainability:
+ SHOPPING_LIST_COLUMNS = [ + "realmID", + "price", + "quantity", + "realmName", + "realmNames", + "link", + ] def petshoppinglist(): # ... - column_order = [ - "realmID", - "price", - "quantity", - "realmName", - "realmNames", - "link", - ] + column_order = SHOPPING_LIST_COLUMNSapp.py (5)
449-449: Remove empty line.There's an unnecessary empty line that should be removed.
Line range hint
1-853: Fix typo in deprecation comments.Throughout the file, "DEPRECIATED" is misspelled. It should be "DEPRECATED".
- # DEPRECIATED + # DEPRECATED
Line range hint
1-853: Consider implementing a more robust deprecation strategy.The current approach of marking routes as deprecated with comments and redirecting could be improved:
- Use proper deprecation warnings
- Consider versioning the API
- Add sunset dates for deprecated routes
- Document migration paths in comments
Example implementation:
from warnings import warn def deprecated_route(func): def wrapper(*args, **kwargs): warn(f"Route {func.__name__} is deprecated and will be removed on YYYY-MM-DD. " f"Please migrate to {new_route_url}", DeprecationWarning, stacklevel=2) return func(*args, **kwargs) return wrapper @app.route("/old-route") @deprecated_route def old_route(): return redirect("https://saddlebagexchange.com/new-route")
Line range hint
9-10: Verify error handling in craftsim_results_table function.The error handling in this function directly returns error messages containing user input, which could lead to information disclosure or XSS.
- return f"error no matching results found matching search inputs:\n {json_data}" + return return_safe_html("No matching results found. Please try different search criteria.")
Line range hint
1-853: Implement request rate limiting consistently.The rate limiting is conditionally applied based on an environment variable, but this could lead to inconsistent protection against abuse.
Consider:
- Always enabling rate limiting in production
- Using different rate limit tiers
- Implementing retry-after headers
- Adding rate limit headers to responses
semgrep.config.yaml (2)
Line range hint
2-850: Consider adding rules for additional security concerns.While the current ruleset is robust, consider adding rules for:
- Secure cookie handling
- CSRF protection
- Security headers
- Password policy enforcement
- Session management
Example rule structure for secure cookie handling:
- id: insecure-cookie-settings pattern-either: - pattern: | $RESPONSE.set_cookie($NAME, $VALUE, secure=False) - pattern: | $RESPONSE.set_cookie($NAME, $VALUE, httponly=False) message: "Cookies should be set with secure and httponly flags" severity: ERROR
851-853: Remove trailing empty lines.There are multiple empty lines at the end of the file that should be removed.

Remove or update deprecated route
The route is marked as deprecated but still being added. The commented redirect suggests moving to a new URL.
Either:
- Implement the redirect
- Remove the deprecated route
- Remove the deprecated comment if still needed

Add input validation for form data
The route accepts form data without validation. Consider adding proper validation:

+ from dataclasses import dataclass
+ from flask import abort
+ @dataclass
+ class ShoppingListRequest:
+ region: str
+ item_id: int
+ max_purchase_price: int

+ max_purchase_price=int(form_data.get('maxPurchasePrice'))
+ )
+ except (ValueError, TypeError):
+ return None
def petshoppinglist():
if request.method == "POST":

+ if not data:
+ abort(400, description="Invalid input data")

10-31: Consider replacing removed Bandit security checksThe removal of the Bandit security checker job could leave the codebase vulnerable to security issues. While Semgrep rules have been added, they may not cover all the security checks that Bandit provided.

- Ensuring all Bandit's critical security checks are covered by equivalent Semgrep rules

450-504: Security review for the petmarketshare route.The route contains several security considerations:
- User input from form data is directly used in the API request without validation
- Error messages expose internal details when NO_RATE_LIMIT is True
- The response data is not sanitized before being rendered in the template
Consider these improvements:
- Add input validation for all form fields
- Use consistent error handling that doesn't expose internal details
- Sanitize the response data before rendering
