Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: The PostgreSQL proxy allowed backend authentication bypasses by proceeding with connection bridging and issuing AuthenticationOK messages to clients despite receiving backend startup errors. Ensure errors close the client socket immediately.
Auth Bypass: Query-protocol services bypassed IAM authorization completely because the registry failed to extract the target 'Action' parameter from application/x-www-form-urlencoded POST bodies, falling back to empty validation.
Path Traversal: Local file-system based S3 storage resolved object keys without validation, enabling attackers to escape the bucket root. Standardize on resolving canonicalized paths and verifying they begin with the bucket root prefix.
