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.\n\n## Affected\n\n- `open_webui >= 0.9.0, < 0.11.1`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `open_webui 0.11.1`\n\n## Package advisory (CVE-2026-87014)\n\nAffected packages:\n\n- `open-webui >= 0.9.0, < 0.11.1`\n\nPatched in:\n\n- `open-webui 0.11.1`\n\nSource: https://osv.dev/vulnerability/GHSA-wjwr-xfp9-r66p","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":35.8,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[]}
