MDJM Event Management and Mobile Events Manager WordPress plugins vulnerabilities

The MDJM Event Management and Mobile Events Manager WordPress plugins through 1.7.8.7 do not check a capability or a nonce before creating a WordPress role from a name supplied in the request, and store that name without escaping it. This allows any authenticated user, such as a subscriber, to inject arbitrary web scripts which execute when an administrator opens one of the standard user management screens.

The MDJM Event Management and Mobile Events Manager WordPress plugins through 1.7.8.7 do not check ownership or capability on the identifier supplied to their client profile update. This allows any authenticated user, such as a subscriber, to change the password and email address of any other account including an administrator, resulting in a full account takeover.

The MDJM Event Management and Mobile Events Manager WordPress plugins through 1.7.8.7 act on a role deletion request on every page load with no capability check and no nonce. The guard meant to protect roles with assigned users reads a different part of the request than the one selecting what is deleted, allowing unauthenticated attackers to remove any WordPress role including administrator, permanently stripping every user of their capabilities.
