public final class UnrestrictedMethodAuthorizer extends Object implements MethodInvocationAuthorizer
MethodInvocationAuthorizer that allows any method execution
as long as the target object does not belong to a Geode package, or does belong but it's marked
as safe (see RestrictedMethodAuthorizer.isAllowedGeodeMethod(Method, Object)).
Some known dangerous methods, like Object.getClass(), are also rejected by this
authorizer implementation, no matter whether the target object belongs to Geode or not
(see RestrictedMethodAuthorizer.isPermanentlyForbiddenMethod(Method, Object)).
This authorizer implementation addresses only three of the four known security risks:
Java Reflection, Cache Modification and Region Modification.
The Region Entry Modification security risk still exists: users with the
DATA:READ:RegionName privilege will be able to execute ANY method (even mutators) on the
objects stored within the region and on instances used as bind parameters of the OQL, so this
authorizer implementation must be used with extreme care.
Usage of this authorizer implementation is only recommended for secured clusters on which only
trusted users and applications have access to the OQL engine. It might also be used on clusters
on which the entries stored are immutable.
