SCA: security update for open-webui (GHSA-6c2x-gcp3-gp73)

medium Tenable Self-Hosted Container Security Plugin ID 441604

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 _validate_collection_access function uses an incomplete allowlist that only enforces
 ownership checks for collections matching user-memory-* and file-* patterns. All other collection names
 pass through unchecked — including the system-level knowledge-bases meta-collection, which stores the IDs,
 names, and descriptions of every knowledge base on the instance. Any authenticated user can query this
 meta-collection directly via the retrieval query endpoints to obtain a global index of all knowledge bases
 across all users. This vulnerability is fixed in 0.9.0. (CVE-2026-44557)

Solution

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