CVE-2026-111671 Details
Description
Cube-studio through 2026.09.01 contains an insecure direct object reference vulnerability that allows authenticated users to stop, reset, clear or redeploy other users' notebooks and services by id. Attackers can pass sequential ids to lifecycle endpoints in view_notebook.py, view_inferenceserving.py and view_serving.py to delete pods and take production inference endpoints offline.
A vulnerability allowing insecure direct object reference (IDOR) has been identified in Cube Studio versions through 2026.09.01. This vulnerability enables authenticated users to manipulate other users' notebooks and services by their IDs. The issue arises from missing authorization checks in custom lifecycle API endpoints, which bypass the intended data isolation between users. As a result, an attacker can disrupt a victim's workflow by stopping or resetting their notebooks, or take down production inference services in different project groups.
The vulnerability can be fixed by adding proper ownership and project-membership checks to the affected lifecycle endpoints, ensuring that only authorized users can access and modify resources.
