Name of the Vulnerable Software and Affected Versions Open WebUI versions 0.8.8 through 0.11.3
Description An improper authorization issue exists where deactivated users can continue executing terminal commands via an active terminal WebSocket. This occurs because the terminal proxy route in terminals.py only verifies access during the initial message, allowing deactivated accounts to maintain the ability to run commands and perform read or write operations on the terminal server.
Recommendations Update Open WebUI to version 0.11.4 or later.
