CVE-2025-14441
WordPress vulnerability analysis and mitigation

The Popupkit plugin for WordPress is vulnerable to arbitrary subscriber data deletion due to missing authorization on the DELETE /subscribers REST API endpoint in all versions up to, and including, 2.2.0. This is due to the permission_callback only validating wp_rest nonce without checking user capabilities. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary subscriber records.
