TIMELINE Jun 11 Reserved by GitHub_M Jun 23 EXPLOIT PUBLISHED — CVE-2026-54019 (open-webui). Public exploit reference added. Jun 23 Published (CNA: GitHub_M)
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.6, Open WebUI added collection-level ACL checks, but the patch can still be bypassed when Milvus multitenancy mode is enabled. The ACL allows unknown non-KB collection names as legacy/ephemeral collections. In Milvus multitenancy mode, that user-controlled collection name becomes a resource_id and is interpolated into a Milvus expression without escaping. This is caused by an incomplete fix for CVE-2026-44560 This vulnerability is fixed in 0.9.6.
