What is known

The UserPlus plugin for WordPress is vulnerable to unauthorized access, modification, and loss of data due to a missing capability check on multiple functions in all versions up to, and including, 2.0.

Business impact

Successful exploitation of CVE-2024-9520, a medium vulnerability (CVSS 6.3) affecting userplus, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.
