Label Studio before 1.23.2 (label-studio-sdk before 2.1.2) contains a server-side request forgery vulnerability that allows authenticated users to read internal URLs through image-bearing export formats. Attackers can import tasks with data.image pointing at internal services, export as YOLO or COCO with images to read responses, and spoof Host to capture the organization owner's API token.
