SCA: security update for open-webui (GHSA-jmc6-2wr8-h3wj)

high Tenable Cloud Security Plugin ID 447896

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 0.8.11 until
 0.11.1, src/lib/components/chat/FileNav/PortPreview.svelte rendered terminal port content in an iframe
 sandbox containing both allow-scripts and allow-same-origin. Because the terminal proxy serves that
 content from the Open WebUI origin, an authenticated user with access to a shared terminal server could
 host script on a previewed port and take over a victim's account when the victim opened the preview. This
 issue is fixed in version 0.11.1. (CVE-2026-87995)

Solution

Update the open-webui library and its related packages to version 0.11.1 or later.
