Overview
open-webui is an Open WebUI
Affected versions of this package are vulnerable to Missing Authorization via the create_folder process. An attacker can create unauthorized folders in another user's account, potentially flooding the victim's folder tree or planting phishing content, by submitting crafted POST requests that include a victim's user ID. This is only exploitable if the attacker has an authenticated account with folder creation permissions and knows or can guess the victim's user UUID.
