      • hasIllegalTypeNameChars

        public static boolean hasIllegalTypeNameChars​(String typeName)
        Tests whether a type name carries a character that cannot appear in a Java binary class name but is meaningful in a URL. A nested jar URL such as jar:http://host/x.jar!/ is resolvable by some class loaders, so a type name carrying one must never reach one.
        Parameters:
        typeName - the type name to test
        Returns:
        true if the type name must be rejected without being resolved

      • normalizeAcceptName

        public static String normalizeAcceptName​(String typeName)
        Normalizes a type name the way the autoType accept-list rolling hash normalizes it, so that a nested class matches whether it is written with its binary name (a.b.Outer$Inner) or its canonical name (a.b.Outer.Inner).
        Parameters:
        typeName - the type name to normalize
        Returns:
        the normalized type name

      • isAutoTypeDenyClass

        public static boolean isAutoTypeDenyClass​(Class<?> type)
        Tests whether a class is a well known deserialization gadget entry point, namely a ClassLoader subclass or a JDK SQL DataSource/RowSet implementation. Such types must not be resolved by matching an autoType whitelist prefix; only an accept entry naming the type in full is treated as an explicit opt-in.
        Parameters:
        type - the class to test
        Returns:
        true if the class must not be resolved through a whitelist prefix match
