[github.com/beego/beego] Access control bypass in beego

The route lookup process in beego through 1.12.4 and 2.x through 2.0.2 allows attackers to bypass access control. When a /p1/p2/:name route is configured, attackers can access it by appending .xml in various places (e.g., p1.xml instead of p1).
