What is CVE-2026-72539?

An information disclosure vulnerability in Windmill Labs' Windmill allows authenticated workspace members to access legacy ownerless draft scripts containing plaintext resource credentials. When drafts have a null owner email, they bypass access control list (ACL) enforcement, enabling any workspace member to query the drafts endpoint and access sensitive stored credentials. This poses a significant risk as it facilitates unauthorized access to sensitive information.
