SCA: security update for open-webui (GHSA-hmgr-67hw-j2cq)

medium Tenable Self-Hosted Container Security Plugin ID 441612

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, the is_user_channel_member function checks whether a ChannelMember row exists but does not check
 the is_active field. When a user is deactivated from a group or DM channel (removed by the channel owner,
 or leaves voluntarily), their membership row persists with is_active=False and status='left'. Because the
 authorization check ignores this field, the deactivated user retains full read and write access to the
 channel via direct API calls. This vulnerability is fixed in 0.9.0. (CVE-2026-44561)

Solution

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