Technical details
An insecure direct object reference (IDOR) vulnerability exists in the /api/project, /api/asset, and /api/script endpoints where auto-increment IDs are not properly scoped to the authenticated user. Attackers can enumerate sequential IDs to access, read, overwrite, cascade-delete, and add themselves as members to projects belonging to other users. The vulnerability requires authentication but allows unauthorized horizontal privilege escalation.
