CVE-2026-59226· NVD / CVE Program· CNA GitHub_M

Open WebUI: Scheduled automations continue after pending-user deactivation and stored model ACL revocation

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.0 before 0.10.0, execute_automation rehydrated automation owners without rechecking that they were still active or still had features.automations, and check_model_access only enforced private-model grants for the exact user role, allowing deactivated pending users to continue scheduled model execution. This issue is fixed in version 0.10.0.
