Post Meta Data Manager <= 1.2.1 - Cross-Site Request Forgery to Post, Term, and User Meta Deletion

Cross-Site Request Forgery (CSRF)
CVE CVE-2023-5776
CVSS Medium (4.3)
Publicly Published November 20, 2023
Last Updated January 22, 2024
Researcher Francesco Carlucci
Description

The Post Meta Data Manager plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.2.1. This is due to missing nonce validation on the pmdm_wp_ajax_delete_meta, pmdm_wp_delete_user_meta, and pmdm_wp_delete_user_meta functions. This makes it possible for unauthenticated attackers to delete arbitrary user, term, and post meta via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
