CVE-2026-109289

5.3 medium SSVC exploitation: none Published
NVD · CVE.org

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.

Fix

Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
