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."}], "lastModified": "2026-06-25T14:27:13.290", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:openwebui:open_webui:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "FAB89FE0-6F34-4624-ABED-8DEE4783A17D", "versionEndExcluding": "0.9.6"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
