Overview
open-webui is an Open WebUI
Affected versions of this package are vulnerable to Incorrect Authorization in the ydoc:document:update handler. An attacker can inject, modify, or delete content in collaborative documents by emitting crafted Socket.IO events after joining a document room with read-only access. If a user with write access subsequently saves the document, the unauthorized changes are persisted. This is only exploitable if the attacker has a valid user account with read access to a shared note and the note is open for collaborative editing.
