Securing Wrapper CodeĀ 

Wrapper code, especially where the wrapper has higher trust than code that uses it, can open a unique set of security weaknesses. Anything done on behalf of a caller, where the caller's limited permissions are not included in the appropriate security check, is a potential weakness to be exploited.

Never enable something through the wrapper that the caller could not do itself. This is a special danger when doing something that involves a limited security check, as opposed to a full stack walk demand. When single-level checks are involved, interposing the wrapper code between the real caller and the API element in question can easily cause the security check to succeed when it should not, thereby weakening security.
