Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Insecure Direct Object Reference (IDOR): Workspace endpoints allowed cross-workspace modifications (GET, PUT, DELETE) because operations trusted user-supplied path parameters without verifying that the authenticated user belonged to the requested workspace. Developers must ensure all workspace-scoped actions use session-derived identifiers.
Auth Bypass: API key validation historically relied on static environment variables rather than database-backed workspace lookup, which allowed authentication bypass and lack of tenant isolation during data querying. Key validation must always cross-reference the workspace database and cache.
