Partially trusted code always presents a security risk. It can sometimes be manipulated to perform actions on behalf of malicious code that does not have permission to access a resource. In this way, malicious code can achieve higher security access than it should be allowed.

The common language runtime helps protect managed code from these attacks by running a stack walk on all calls. The stack walk requires that all code in the call stack has permission to access a protected resource. Because the code attempting the attack will always be somewhere in the call stack, it will be unable to exceed its own security permissions.
