{"id":"CVE-2026-59213","summary":"Open WebUI: Cross-user model-list exposure via static cache key in get_all_models (aiocache key= vs key_builder= misuse)","details":"Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.6.27 before 0.10.0, get_all_models handlers in routers/openai.py and routers/ollama.py passed a lambda to aiocache key instead of key_builder, causing permission-filtered per-user model lists to share a static cache entry and exposing one user’s model list to another caller during the TTL window. This issue is fixed in version 0.10.0.","aliases":["GHSA-3wp3-xxj9-5jqq"],"modified":"2026-07-15T01:48:51.837250768Z","published":"2026-07-09T16:55:00.032Z","database_specific":{"cwe_ids":["CWE-524"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59213.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/open-webui/open-webui/releases/tag/v0.10.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59213.json"},{"type":"ADVISORY","url":"https://github.com/open-webui/open-webui/security/advisories/GHSA-3wp3-xxj9-5jqq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59213"},{"type":"FIX","url":"https://github.com/open-webui/open-webui/commit/0fc630b34b2899599dabffffa012afd47599aa75"},{"type":"FIX","url":"https://github.com/open-webui/open-webui/pull/25783"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/open-webui/open-webui","events":[{"introduced":"918f507d8cdc652ae913b8596877a8a50b845114"},{"fixed":"4d2e13cf2bcc451b33bb6374bea4d2163e6cc94c"},{"fixed":"0fc630b34b2899599dabffffa012afd47599aa75"}],"database_specific":{"extracted_events":[{"introduced":"0.6.27"},{"fixed":"0.10.0"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:openwebui:open_webui:*:*:*:*:*:*:*:*"}}],"versions":["v0.9.5","v0.9.4","v0.9.3","v0.9.2","v0.9.1","v0.9.0","v0.8.12","v0.8.11","v0.8.10","v0.8.9","v0.8.8","v0.8.7","v0.8.6","v0.8.5","v0.8.4","v0.8.3","v0.8.2","v0.8.1","v0.8.0","v0.7.2","v0.7.1","v0.7.0","v0.6.43","v0.6.42","v0.6.41","v0.6.40","v0.6.39","v0.6.38","v0.6.37","v0.6.36","v0.6.34","v0.6.35","v0.6.33","v0.6.32","v0.6.31","v0.6.30","v0.6.29","v0.6.28","v0.6.27"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-59213.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:N/A:N"}]}
