SCA: security update for open-webui (GHSA-8x5v-cpv7-8jjp)

high Tenable Cloud Security Plugin ID 445653

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 0.9.0 until
 0.11.0, Open WebUI checked whether a user-supplied URL destination was globally routable by applying
 ipaddress.is_global to the literal IPv6 address without examining IPv4 addresses embedded in transition
 encodings. On a deployment with a NAT64 gateway, any verified user could wrap an internal or cloud-
 metadata IPv4 address in the NAT64 well-known prefix, pass the filter, and receive the internal response
 body through RAG URL ingestion, URL-to-markdown conversion, or web-search content retrieval. This issue is
 fixed in 0.11.0. (CVE-2026-70485)

Solution

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