CVE-2022-31259
Access control bypass in beego
The route lookup process in beego before 1.12.9 and 2.x before 2.0.3 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).

OSVGO-2022-0463 No score
Access control bypass due to broad route matching in github.com/beego/beego and beego/v2
Routes in the beego HTTP router can match unintended patterns. This overly-broad matching may permit an attacker to bypass access controls.
For example, the pattern "/a/b/:name" can match the URL "/a.xml/b/". This may bypass access control applied to the prefix "/a/".
