SCA: security update for open-webui (GHSA-pwxh-7358-jq2x)

high Tenable Self-Hosted Container Security Plugin ID 445650

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 0.10.0 until
 0.11.0, src/lib/components/chat/Messages/Markdown/KatexRenderer.svelte could store and render a chat
 message whose math block makes KaTeX fail with a stack overflow instead of a parse error. The catch branch
 fell back to inserting the original math source into the page as HTML through {@html} rather than as text,
 so script in the message runs in the browser of whoever views it, including shared chats and channels. The
 viewer's session token in localStorage can be stolen, and an administrator viewer can have their account
 taken over. This issue is fixed in 0.11.0. (CVE-2026-70492)

Solution

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