Technical details
A cross-tenant Insecure Direct Object Reference (IDOR) vulnerability exists in Maxun versions prior to 0.0.42 due to missing authorization checks in the storage and webhook API handlers. The root cause is a failure to validate ownership of resources (CWE-862), where API endpoints like /robots would return all records instead of scoping results to the authenticated user's ID. A remote attacker with low-privileged credentials can exploit this to read plaintext OAuth tokens for Google and Airtable, or modify, delete, and execute robots belonging to other tenants. The issue was addressed in version 0.0.42 by enforcing user-id scoping across all robot-related API endpoints.
