## Affected

- mdjm MDJM Event Management: through 1.7.8.1

## Description

The MDJM Event Management plugin for WordPress is vulnerable to unauthorized data modification due to a missing capability check on the 'custom_fields_controller' function in all versions up to, and including, 1.7.8.1. This makes it possible for unauthenticated attackers to delete arbitrary custom event fields via the 'delete_custom_field' and 'id' parameters.
