SCA: security update for open-webui (GHSA-9rpj-v7hf-vv2w)

medium Tenable Self-Hosted Container Security Plugin ID 443375

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 0.9.6, several direct, index-addressed Ollama proxy routes accept a caller-supplied url_idx path
 parameter and use it as a raw index into the admin-configured OLLAMA_BASE_URLS list. Access control on
 these routes validates only whether the user may use the requested model, never which backend the request
 is routed to. Any authenticated user can append an arbitrary url_idx to force their request onto an Ollama
 backend they were never authorized to reach, including internal, higher-privilege, or explicitly admin-
 disabled backends. This vulnerability is fixed in 0.9.6. (CVE-2026-54021)

Solution

Update the open-webui library and its related packages to version 0.9.6 or later.
