{"id":"CVE-2025-14441","state":"PUBLISHED","title":"Popupkit <= 2.2.0 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Subscriber Data Deletion","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.","publishedAt":"2026-01-06T04:31:55.856Z","updatedAt":"2026-04-08T16:50:20.931Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["roxnor Popup builder with Gamification, Multi-Step Popups, Page-Level Targeting, and WooCommerce Triggers"],"affected":[{"vendor":"roxnor","product":"Popup builder with Gamification, Multi-Step Popups, Page-Level Targeting, and WooCommerce Triggers","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.2.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/48f5a44d-d01f-4c41-98da-7c1f6c65c254?source=cve","https://plugins.trac.wordpress.org/browser/popup-builder-block/trunk/includes/Routes/Subscribers.php#L77","https://plugins.trac.wordpress.org/browser/popup-builder-block/tags/2.2.0/includes/Routes/Subscribers.php#L77","https://plugins.trac.wordpress.org/browser/popup-builder-block/tags/2.2.0/includes/Routes/Subscribers.php#L64","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3421671%40popup-builder-block&new=3421671%40popup-builder-block&sfp_email=&sfph_mail="],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:08:31.050Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/14xxx/CVE-2025-14441.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-14441","state":"PUBLISHED","datePublished":"2026-01-06T04:31:55.856Z","dateUpdated":"2026-04-08T16:50:20.931Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2025-12-10T13:07:03.705Z"},"containers":{"cna":{"title":"Popupkit <= 2.2.0 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Subscriber Data Deletion","descriptions":[{"lang":"en","value":"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.
