MDJM Event Management and Mobile Events Manager <= 1.7.8.7 - Unauthenticated Arbitrary Role Deletion

Description

The plugins act on a role deletion request on every page load with no capability check and no nonce, and the guard meant to protect roles that have users assigned reads a different part of the request from the one that selects what is deleted, allowing unauthenticated attackers to remove any WordPress role including administrator, which permanently strips every user of their capabilities.
