Overview
open-webui is an Open WebUI
Affected versions of this package are vulnerable to Incorrect Authorization in the is_user_channel_member function. An attacker can retain unauthorized read and write access to group or direct message channels by making direct API calls after being deactivated from the channel. This is only exploitable if the channels feature is enabled, the attacker has a valid user account, and the attacker was previously a member of the channel (and thus knows the channel ID).
