Prior to 0.9.0, FolderForm uses model_config = ConfigDict(extra=&#39;allow&#39;), which permits arbitrary fields to pass through Pydantic validation and be included in model_dump(exclude_unset=True). In insert_new_folder, the server-assigned user_id is placed at the start of the dict and then overwritten by the spread of form data. Because FolderModel declares user_id: str as a real field (not just a form extra), any attacker-supplied user_id in the POST body is accepted by the model and persisted on the Folder row. This vulnerability is fixed in 0.9.0.</p> <p><strong>Affected:</strong> open-webui</p> <p>Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline.
