Overview
open-webui is an Open WebUI
Affected versions of this package are vulnerable to Missing Authorization in the get_channel_members_by_id process. An attacker can retrieve the list of users, including their IDs, names, emails, roles, and profile images, associated with a private channel by making an authenticated API call to the affected endpoint if they possess the channel's UUID. This is only exploitable if the channels feature is enabled and the attacker knows the channel UUID.
