Summary

Cube-studio from 0 through 2026.09.01 is affected. A missing object-level authorization check (CWE-639) lets authenticated users act on other users' notebooks and services by id. An attacker with low privileges can stop, reset, clear or redeploy them by passing sequential ids, which can delete pods and take production inference endpoints offline.
