JDK then calls the default \nObjectInputStream.resolveProxyClass(interfaces) implementation, which \nperforms Class.forName(intf, false, latestUserDefinedLoader()) for EACH \ninterface name and constructs the proxy class — bypassing the accepted\n classes list .\n\n\nZDRES-233: Class.forName(name, initialize=true, classLoader) in \nreadClassDescriptor Triggers Static Initialiser of Allow-Listed Classes\n\n\nAssessment: Fully addressed.\n\n\nFor ANY class on the allow-list, deserialising a stream that names it triggers the class’s \n (static initialiser) BEFORE any instance is constructed. This means an \nattacker who supplies a class name on the allow-list (e.g., the \ndeveloper wrote accept(“com.myapp.*\") , attacker supplies \ncom.myapp.SomeClass ) causes \u003cclinit\u003e of SomeClass — and many \nreal-world classes have side-effecting static initialisers\n\n\nBoth issues have been fixed.",
