SCA: security update for open-webui (GHSA-jgj3-r8hr-9pjw)

medium Tenable Cloud Security Plugin ID 442200

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 0.8.6, in standard channels (i.e., channels whose channel.type is neither group nor dm), the endpoint
 POST /api/v1/channels/{channel_id}/messages/{message_id}/update can be accessed with read permission only.
 When access_control is set to None, the authorization check has_access(..., type="read") evaluates to
 True, allowing users who are not the message owner to update messages. As a result, unauthorized
 modification of other users’ messages is possible. This vulnerability is fixed in 0.8.6. (CVE-2026-44571)

Solution

Update the open-webui library and its related packages to version 0.8.6 or later.
