## Overview

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).

## Affected packages

- `github.com/beego/beego/v2 < 2.0.3`
- `github.com/beego/beego < 1.12.9`

## Remediation

Upgrade to a patched release:

- `github.com/beego/beego/v2 2.0.3`
- `github.com/beego/beego 1.12.9`
