Miggo AIRoot Cause Analysis

The advisory explicitly mentions a form validation() method with missing permission checks and CSRF protection. In Jenkins plugins, connection test endpoints (like doTest* methods) in DescriptorImpl classes are common vectors for such issues. The combination of missing @RequirePOST annotation (allowing GET access) and lack of permission validation matches the described vulnerability pattern. This aligns with Jenkins' security best practices where form validation() methods require POST requests and proper authorization checks.
