CVE-2019-16567: Jenkins Team Concert Plugin missing permission check

The vulnerability description explicitly mentions missing permission checks in form-related methods that allow credential ID enumeration. Jenkins plugins typically use 'doFill[Field]Items' methods to populate dropdown lists in configuration forms. These methods are vulnerable when they lack @RequirePermissions annotations or equivalent authorization checks. The advisory specifically references credential ID exposure through form validation, which aligns with this common Jenkins plugin pattern.
