Title

Windmill Labs Windmill - Information Disclosure

Summary

An information disclosure vulnerability in Windmill Labs Windmill through 1.783.0 allows any authenticated workspace member to read legacy ownerless draft scripts that contain plaintext resource credentials. Drafts with a null owner email bypass ACL enforcement and are returned to any workspace member who queries the drafts endpoint. Sensitive credentials stored in these drafts are exposed across ACL boundaries.
