Creating or modifying a custom Credential\nType requires Controller superuser; an organization Credential Admin can weaponize a\npre-existing malicious custom type by supplying its input. Managed credential types\ncannot be edited and are unaffected. The control that is bypassed exists specifically\nto prevent credential injectors from hijacking the runner process, so its incomplete\ndeny-list is a security defect (CWE-184) rather than expected behavior, and in\nGateway-managed deployments (AAP 2.5+) it crosses the platform-admin -> execution-\nenvironment/host boundary.
