Overview
open-webui is an Open WebUI
Affected versions of this package are vulnerable to Incorrect Authorization through the caching of user roles on active Socket.IO connections during SSO-driven role changes. An attacker can retain unauthorized read and write access to other users' private notes by maintaining an open socket connection after being demoted from an elevated role via SSO role synchronization. This is only exploitable if SSO role-sync is enabled (either trusted-header authentication with WEBUI_AUTH_TRUSTED_ROLE_HEADER set or OAuth role mapping enabled), and the demotion occurs through the identity provider while the socket connection remains open.
