CVE-2023-5425: Wpexpertplugins Post Meta Data Manager

High severity, CVSS 8.8. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Wpexpertplugins Post Meta Data Manager: before 1.2.1 (fixed in 1.2.1)
