**Title:** Scheduled automations continue after pending-user deactivation and stored model ACL revocation ### Summary Open WebUI documents `pending` as a zero-access role used for new sign-ups and deactivated users, and normal HTTP routes enforce that with `get_verified_user()` (which rejects `pending`), while automation create/update/run routes additionally require the `features.automations` permission. Two paths missed that lifecycle gate, so a deactivated (`pending`) account could keep acting through the background automation scheduler: 1. **Scheduler did not re-gate the owner.** When a stored automation became due, `execute_automation()` rehydrated the owner with `Users.get_user_by_id(...)` and re-entered the chat completion pipeline without re-checking that the owner was still `user`/`admin` or still held `features.automations`. A still-active automation therefore kept running after its owner was deactivated. 2. **Model ACL only enforced for exact role `user`.** `check_model_access()` applied private-model grants only when `user.role == "user"`, so a `pending` principal fell through a branch that denies a normal non-owner `user`. Net effect: a deactivated account could con

What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
