EPSS · scored 2026-10-27

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).

GHSA-qx32-f6g6-fcfrAccess control bypass in beego2022-05-22ghsa · osvUS
The route lookup process in beego prior to 1.12.9 and 2.x prior to 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).
GO-2022-0463Access control bypass due to broad route matching in github.com/beego/beego and beego/v22022-07-01vendor · osvUS
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/".
