What is CVE-2023-5426?

The Post Meta Data Manager plugin for WordPress has a vulnerability that allows unauthenticated attackers to delete user, term, and post meta data. This issue arises from a lack of proper capability checks in the pmdm_wp_delete_user_meta, pmdm_wp_delete_term_meta, and pmdm_wp_ajax_delete_meta functions in versions up to and including 1.2.0. As a result, attackers can maliciously manipulate data belonging to any user, leading to potential data loss and integrity issues.

Affected Version(s)

Post Meta Data Manager * <= 1.2.0
