Summary
The MDJM Event Management and Mobile Events Manager WordPress plugins through 1.7.8.7 let unauthenticated attackers delete any WordPress role, including administrator. A role deletion request runs on every page load with no capability check or nonce, and a guard meant to protect roles with users reads a different part of the request than the one selecting the deleted role (CWE-862). Deleting the administrator role strips every user of their capabilities. A public exploit is linked in the references.

Description from the CNA
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, 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.
