MediumCVSS 6.5Summary
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.

Exposure of credentials can lead to unauthorized access to resources and security breaches.
Recommendation
Update Windmill to a version that enforces access control for ownerless scripts.
