SCA: security update for open-webui (GHSA-rffm-9q57-q649)

medium Tenable Self-Hosted Container Security Plugin ID 445676

Description

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

 - Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.6.34 until
 0.11.0, Open WebUI renders vega and vega-lite fenced code blocks in chat content by building a Vega view
 in the viewer browser without a restricted resource loader. Any user who can place such a block where
 another user will see it can make that user browser issue attacker-chosen outbound GET requests and read
 responses from same-origin or CORS-permissive targets into the rendered page. This issue is fixed in
 0.11.0. (CVE-2026-70480)

Solution

Update the open-webui library and its related packages to version 0.11.0 or later.
