Advisory
Source description from Wordfence Intelligence, credited to Drew Jones.
The Reviews Plus plugin for WordPress is vulnerable to Denial of Service in versions before 1.2.14. This is due to an unknown part of the file post/page of the component Rating Submission Handler. The manipulation with an unknown input leads to a denial of service vulnerability. This makes it possible for authentication attackers, a authentication is necessary for exploitation to cause a Denial of Service in the review section when an authenticated user submit such rating and the reviews are set to be displayed on the post/page.
