CVE-2022-31259 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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).. EPSS estimates a 21.57% chance of exploitation in the next 30 days.
