CVE-2023-5776

Name of the Vulnerable Software and Affected Versions Post Meta Data Manager plugin for WordPress versions up to, and including, 1.2.1

Description The issue 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, making it possible for unauthenticated attackers to delete arbitrary user, term, and post meta via a forged request. This can be achieved if an attacker can trick a site administrator into performing an action, such as clicking on a link.

Recommendations For versions up to, and including, 1.2.1, update to a version that includes nonce validation for the pmdm wp ajax delete meta, pmdm wp delete user meta, and pmdm wp delete user meta functions to prevent Cross-Site Request Forgery attacks. As a temporary workaround, consider restricting access to these functions until a patch is available.
