Summary
The CMP WordPress plugin before version 4.1.18 does not enforce an option-name allow-list when importing settings via one of its AJAX actions, allowing users with the Editor role (when the administrator has granted the Editor role access to the CMP plugin's admin-bar controls) to update arbitrary WordPress options, including options that lead to privilege escalation to Administrator.
Risk Assessment
An attacker with the Editor role can escalate privileges to Administrator, gaining full control over the WordPress installation, including the ability to modify files, install malware, and steal data.
Recommendation
It is recommended to immediately update the CMP plugin to version 4.1.18 or later and review the permissions granted to users with the Editor role.
