## HIGH-Severity Lambda Vulnerability: Detailed Error Messages Expose System Internals to Attackers
A critical information disclosure vulnerability has been identified across all Lambda functions within a major codebase, exposing detailed system internals through error messages. The flaw, rated HIGH severity, allows attackers to gather significant reconnaissance data, including full stack traces, internal file paths, and implementation details, which can be leveraged for further exploitation. This exposure fundamentally undermines security by revealing the underlying code structure and dependencies to any external party triggering an error.

The vulnerability resides in the `website/lambda/*.py` files, where exception handling code returns excessive diagnostic information to the client. The current, vulnerable implementation includes the raw exception message (which may contain sensitive data), the full Python traceback, the executing file's path, and internal function names in its HTTP 500 error responses. This practice turns routine operational failures into a goldmine for attackers, providing a clear map of the application's architecture and potential weak points.

This information leakage poses a direct risk to system integrity. By exposing file paths and code structure, it simplifies an attacker's job in identifying specific components for targeted attacks. The recommended fix is to implement generic, user-friendly error messages that do not reveal internal system details, a standard security practice for production environments. Failure to remediate this flaw leaves the entire application surface area more transparent and vulnerable to subsequent, more precise security breaches.
