Overview
open-webui is an Open WebUI
Affected versions of this package are vulnerable to Missing Authorization through the improper validation of the meta.knowledge field during model creation, update, or import processes. An attacker can gain unauthorized access to and delete files belonging to other users by forging file IDs in the meta.knowledge metadata and leveraging built-in tools such as view_file. This is only exploitable if the attacker has permissions to create, update, or import workspace models and knows the victim's file ID.
