- Summary
- Open WebUI: Sign-in as another user via wildcard characters in the OAuth subject claim on SQLite
- Details
-
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.6.41 until 0.11.1, get_user_by_oauth_sub and get_user_by_scim_external_id in backend/open_webui/models/users.py used JSON contains matching that compiled to SQL LIKE substring matching on SQLite. An OAuth subject containing percent or underscore wildcard characters could resolve to a different stored identity, potentially selecting an administrator account and issuing the attacker that account's session; PostgreSQL deployments were not affected. This issue is fixed in version 0.11.1.
