What the vulnerability does

01Description

The Post Meta Data Manager plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the pmdm_wp_change_user_meta and pmdm_wp_change_post_meta functions in versions up to, and including, 1.2.0. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to gain elevated (e.g., administrator) privileges.
