SCA: security update for open-webui (GHSA-3x8w-4f7p-xxc2)

high Tenable Cloud Security Plugin ID 441613

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 tool_servers and terminal_servers keys in utils/tools.py do use a prefix. When two or more
 Open WebUI instances share a Redis database (a supported and documented deployment pattern, e.g., for
 multi-region deployments, blue-green setups, or cluster topologies), the unprefixed keys collide. An admin
 on Instance A writing to tool_servers overwrites the value read by Instance B — causing Instance B's users
 to receive Instance A's tool server configuration. This vulnerability is fixed in 0.9.0. (CVE-2026-44552)

Solution

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