CVE Vulnerability

CVE-2020-36157

An issue was discovered in the Ultimate Member plugin before 2.1.12 for WordPress, aka Unauthenticated Privilege Escalation via User Roles. Due to the lack of filtering on the role parameter that could be supplied during the registration process, an attacker could supply the role parameter with a WordPress capability (or any custom Ultimate Member role) and effectively be granted those privileges.
