SCA: security update for open-webui (GHSA-rcvp-6fgw-c7fh)

medium Tenable Cloud Security Plugin ID 441617

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 0.9.0, the /api/generate, /api/embed, /api/embeddings, and /api/show endpoints accept any model name
from the user and forward the request to the Ollama backend without checking whether the user is
authorized to access that model. These endpoints only require get_verified_user (any authenticated non-
pending user) and validate that the model exists in the full unfiltered model list, but never check
AccessGrants.has_access(). This vulnerability is fixed in 0.9.0. (CVE-2026-44563)

Solution

Update the open-webui library and its related packages to version 0.9.0 or later.
