{"id":"CVE-2026-87014","summary":"Open WebUI: Admin demoted through SSO role sync keeps read and write access to all users' notes","details":"Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.0 until 0.11.1, role synchronization in backend/open_webui/routers/auths.py and backend/open_webui/utils/oauth.py updated an administrator's database role without invalidating the user record cached by backend/open_webui/socket/main.py. An administrator demoted through a trusted role header or OAuth role mapping could keep an already-open Socket.IO connection and continue reading or editing every user's collaborative notes until that connection closed. This issue is fixed in version 0.11.1.","aliases":["GHSA-wjwr-xfp9-r66p"],"modified":"2026-09-12T03:31:01.384777121Z","published":"2026-09-09T21:01:39.505Z","database_specific":{"cwe_ids":["CWE-613","CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/87xxx/CVE-2026-87014.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/open-webui/open-webui/releases/tag/v0.11.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/87xxx/CVE-2026-87014.json"},{"type":"ADVISORY","url":"https://github.com/open-webui/open-webui/security/advisories/GHSA-wjwr-xfp9-r66p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-87014"},{"type":"FIX","url":"https://github.com/open-webui/open-webui/commit/ce3c175e260709f359d7e6cbb3132f0572098b95"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/open-webui/open-webui","events":[{"introduced":"f31768e20e5c6b4f6da0ef657877298b359936cf"},{"fixed":"ce3c175e260709f359d7e6cbb3132f0572098b95"},{"fixed":"d3e8bf3405e848cfba377814d0aa7ba7290e414d"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0.9.0"},{"fixed":"0.11.1"}]}}],"versions":["v0.11.0","v0.10.2","v0.10.1","v0.10.0","v0.9.5","v0.9.4","v0.9.3","v0.9.2","v0.9.1","v0.9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-87014.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N"}]}
