Detailsinfo

A vulnerability classified as problematic was found in open-webui Open WebUI up to 0.8.x. This vulnerability affects some unknown processing.

The product does not perform an authorization check when an actor attempts to access a resource or perform an action. As an impact it is known to affect integrity. CVE summarizes:

Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, FolderForm uses model_config = ConfigDict(extra='allow'), 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.

The advisory is available at github.com. This vulnerability was named CVE-2026-44550 since 05/06/2026. The exploitation appears to be easy. The attack can be initiated remotely. The technical details are unknown and an exploit is not available.
