Open WebUI 0.8.8 before 0.11.4 Improper Session Revocation via Terminal WebSocket

Type: advisorySource: Official CVE List1 source record

Open WebUI from 0.8.8 before 0.11.4 contains an improper authorization vulnerability that allows deactivated users to keep executing terminal commands through an already open terminal WebSocket. Because the terminal proxy route in terminals.py checks access only on the first message, deactivated users can keep running commands and reading or writing files on the terminal server.
