Overview
open-webui is an Open WebUI
Affected versions of this package are vulnerable to Incorrect Authorization through the meta.knowledge process. An attacker can gain unauthorized write or delete access to files belonging to other users by attaching a file ID, for which they only have read access via a knowledge-base grant, to an attacker-controlled workspace model. This allows the attacker to rename, overwrite, or delete files that should only be accessible to the file owner or admin. This is only exploitable if the attacker is an authenticated non-admin user with Models workspace access and has read-only access to the victim file through a knowledge-base grant.
