Class: java.io.SerializablePermission

This class is for Serializable permissions. A SerializablePermission contains a name (also referred to as a "target name") but no actions list; you either have the named permission or you don't.

The target name is the name of the Serializable permission (see below).

The following table lists all the possible SerializablePermission target names, and for each provides a description of what the permission allows and a discussion of the risks of granting code the permission.

Permission Target NameWhat the Permission AllowsRisks of Allowing this Permission
enableSubclassImplementationSubclass implementation of ObjectOutputStream or ObjectInputStream to override the default serialization or deserialization, respectively, of objectsCode can use this to serialize or deserialize classes in a purposefully malfeasant manner. For example, during serialization, malicious code can use this to purposefully store confidential private field data in a way easily accessible to attackers. Or, during deserialization it could, for example, deserialize a class with all its private fields zeroed out.
enableSubstitutionSubstitution of one object for another during serialization or deserializationThis is dangerous because malicious code can replace the actual object with one which has incorrect or malignant data.
