Primary sources: NVD · CVE.org · FIRST EPSS

The UserPro plugin for WordPress is vulnerable to unauthorized access of data, modification of data, loss of data due to a missing capability check on multiple functions in all versions up to, and including, 5.1.1. This makes it possible for unauthenticated attackers to add, modify, or delete user meta and plugin options.
