Angular Expressions before version 1.0.1 has a remote code execution vulnerability if you call expressions.compile(userControlledInput) where userControlledInput is text that comes from user input.

If running angular-expressions on the server, an attacker could run any Javascript expression, thus gaining Remote Code Execution.
