Overview
open-webui is an Open WebUI
Affected versions of this package are vulnerable to Missing Authorization through the import_models process. An attacker can overwrite existing models owned by other users, modify their configuration, and escalate access by submitting crafted payloads to the model import endpoint without ownership or access grant validation. This is only exploitable if the attacker has the workspace.models_import permission and knows the target model's ID.
