Summary

Open WebUI: Mass Assignment via Pydantic extra='allow' Allows Creating Folders in Other Users' Accounts

Details

Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, FolderForm uses modelconfig = ConfigDict(extra='allow'), which permits arbitrary fields to pass through Pydantic validation and be included in modeldump(excludeunset=True). In insertnewfolder, the server-assigned userid is placed at the start of the dict and then overwritten by the spread of form data. Because FolderModel declares userid: str as a real field (not just a form extra), any attacker-supplied userid in the POST body is accepted by the model and persisted on the Folder row. This vulnerability is fixed in 0.9.0.
