What is CVE-2023-5776?

The Post Meta Data Manager plugin for WordPress is susceptible to Cross-Site Request Forgery (CSRF) vulnerabilities in all versions up to and including 1.2.1. This arises from the lack of nonce validation in functions like pmdm_wp_ajax_delete_meta, pmdm_wp_delete_user_meta, and pmdm_wp_delete_user_meta. As a result, unauthenticated attackers can exploit this weakness to delete arbitrary user, term, and post metadata, provided they can deceive a site administrator into executing a specific action, such as clicking on a malicious link.
