Data Exposure in Flask
Flask-Specific Remediation
Fixing data exposure in Flask requires both configuration changes and code-level protections. Here are specific remediation strategies:
Disable Debug Mode in Production - This is the most critical fix:

Frequently Asked Questions
How can I test if my Flask API has debug mode enabled?
Make a request to your Flask API and look for Werkzeug debugger headers, stack traces, or debug information in responses. You can also check if the response includes 'werkzeug' in the server header or if error responses contain detailed traceback information. middleBrick automatically detects debug mode through response analysis and will flag it as a critical vulnerability.
What's the difference between CORS misconfiguration and data exposure?
CORS misconfiguration is a specific type of data exposure vulnerability. When CORS is too permissive (origins='*'), it allows any website to make requests to your API and potentially access sensitive data through the browser. This isn't a direct data leak, but it enables cross-origin data access that should be restricted. middleBrick tests CORS policies by making requests from different origins and analyzing the Access-Control-Allow-Origin headers.
