From 0.8.12 before 0.10.0, an authenticated non-admin user with read access to an arena wrapper model can reach a restricted underlying model through task endpoints such as /api/v1/tasks/moa/completions. The normal chat route resolves arena models before the final chat dispatch and therefore re-checks the selected underlying model. The task routes call utils.chat.generate_chat_completion() directly. In that direct path, arena fallback resolution happens after the wrapper access check and then recurses with bypass_filter=True, skipping the selected submodel's access check. This issue is fixed in version 0.10.0."}], "lastModified": "2026-07-10T02:44:19.193", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:openwebui:open_webui:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "760C3A19-5111-498B-87C0-649AD707A809", "versionEndExcluding": "0.10.0", "versionStartIncluding": "0.8.12"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
