For an application to be vulnerable, polymorphic type validation must be configured to process untrusted input with class-name identifiers, and exploitable gadget classes must exist on the classpath. In standard Red Hat product configurations, permissive class-name polymorphism is not enabled by default on external interfaces, significantly limiting exposure in typical production environments.",
