Summary

The CMP WordPress plugin before 4.1.18 does not sanitise and escape a settings value before outputting it on the coming-soon page, allowing users with the Editor role (when the administrator has granted the Editor role access to the CMP WordPress plugin before 4.1.18's admin-bar controls) to inject arbitrary web scripts that execute when a visitor views the page.
