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&#39;s users to receive Instance A&#39;s tool server configuration. This vulnerability is fixed in 0.9.0.</p> <p><strong>Affected:</strong> open-webui</p> <p>Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline.
