beego is an open-source web framework for the Go programming language. Versions of beego prior to 2.3.4 use MD5 as a hashing algorithm. MD5 is no longer considered secure against well-funded opponents due to its vulnerability to collision attacks. Version 2.3.4 replaces MD5 with SHA256.

An issue in beego v.2.2.0 and before allows a remote attacker to escalate privileges via the getCacheFileName function in file.go file

An issue in beego v.2.2.0 and before allows a remote attacker to escalate privileges via the sendMail function located in beego/core/logs/smtp.go file

The leafInfo.match() function in Beego v2.0.3 and below uses path.join() to deal with wildcardvalues which can lead to cross directory risk.

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).

An issue was discovered in the route lookup process in beego before 1.12.11 that allows attackers to bypass access control.

An issue was discovered in file profile.go in function GetCPUProfile in beego through 2.0.2, allows attackers to launch symlink attacks locally.

An issue was discovered in file profile.go in function MemProf in beego through 2.0.2, allows attackers to launch symlink attacks locally.

Cross Site Scripting (XSS) vulnerability exists in the admin panel in Beego v2.0.1 via the URI path in an HTTP request, which is activated by administrators viewing the "Request Statistics" page.

The File Session Manager in Beego 1.10.0 allows local users to read session files because of weak permissions for individual files.
