SCA: security update for open-webui (GHSA-45m8-cpm2-3v65)

high Tenable Self-Hosted Container Security Plugin ID 441623

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior
 to 0.9.0, administrative role changes and user deletions do not iterate SESSION_POOL to disconnect
 affected sessions. As a result, a user whose admin role has been revoked retains admin privileges within
 their existing Socket.IO session for as long as they keep the connection alive (via automatic heartbeats).
 The gap is exclusive to the Socket.IO session cache. This vulnerability is fixed in 0.9.0.
 (CVE-2026-44553)

Solution

Update the open-webui library and its related packages to version 0.9.0 or later.
