In open-webui/open-webui version v0.3.8, there is an improper privilege management vulnerability. The application allows an attacker, acting as an admin, to delete other administrators via the API endpoint
http://0.0.0.0:8080/api/v1/users/{uuid_administrator}. This action is restricted by the user interface but can be performed through direct API calls.References
