CVE-2025-14441 – Popupkit

CVE ID : CVE-2025-14441

Published : Jan. 6, 2026, 5:15 a.m. | 1 hour, 11 minutes ago

Description : 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.

Severity: 5.3 | MEDIUM
