Access violation vulnerability in Multiple Roles 1.3.7

The Multiple Roles plugin for WordPress is a software that can be used in websites running the WordPress platform. Unfortunately, versions before 1.3.7 of the software have a vulnerability which can allow attackers to gain access to parts of the website that they should not have access to. If an attacker gains access to the website, they can use the vulnerability to increase their privileges, allowing them to do more than they should be able to. It is important that users of this plugin update to the latest version of the software in order to remain secure.
