public final class SerializablePermission extends BasicPermission
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 Name | What the Permission Allows | Risks of Allowing this Permission |
|---|---|---|
| enableSubclassImplementation | Subclass implementation of ObjectOutputStream or ObjectInputStream to override the default serialization or deserialization, respectively, of objects | Code 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. |
| enableSubstitution | Substitution of one object for another during serialization or deserialization | This is dangerous because malicious code can replace the actual object with one which has incorrect or malignant data. |
