Description
bisheng through 2.6.0-fix2 contains a server-side request forgery vulnerability in the POST /api/v1/workflow/report/callback endpoint that lacks authentication and applies no URL scheme restrictions or host filtering. Unauthenticated attackers can supply arbitrary URLs to enumerate internal network services and cloud metadata endpoints, then retrieve captured responses from object storage using caller-supplied object names.
