{"id":"CVE-2026-4283","state":"PUBLISHED","title":"WP DSGVO Tools (GDPR) <= 3.1.38 - Missing Authorization to Unauthenticated Account Destruction of Non-Admin Users","description":"The WP DSGVO Tools (GDPR) plugin for WordPress is vulnerable to unauthorized account destruction in all versions up to, and including, 3.1.38. This is due to the `super-unsubscribe` AJAX action accepting a `process_now` parameter from unauthenticated users, which bypasses the intended email-confirmation flow and immediately triggers irreversible account anonymization. This makes it possible for unauthenticated attackers to permanently destroy any non-administrator user account (password randomized, username/email overwritten, roles stripped, comments anonymized, sensitive usermeta wiped) by submitting the victim's email address with `process_now=1`. The nonce required for the request is publicly available on any page containing the `[unsubscribe_form]` shortcode.","publishedAt":"2026-03-24T04:27:50.054Z","updatedAt":"2026-04-08T16:41:24.691Z","severity":{"score":9.1,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["legalweb WP DSGVO Tools (GDPR)"],"affected":[{"vendor":"legalweb","product":"WP DSGVO Tools (GDPR)","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.1.38","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/21389122-cb39-45d1-a889-b830d3a55603?source=cve","https://plugins.trac.wordpress.org/browser/shapepress-dsgvo/tags/3.1.38/public/shortcodes/super-unsubscribe/unsubscribe-form-action.php#L39","https://plugins.trac.wordpress.org/browser/shapepress-dsgvo/tags/3.1.38/includes/models/unsubscriber.php#L24","https://plugins.trac.wordpress.org/browser/shapepress-dsgvo/tags/3.1.38/includes/class-sp-dsgvo-data-collecter.php#L250","https://plugins.trac.wordpress.org/browser/shapepress-dsgvo/trunk/public/shortcodes/super-unsubscribe/unsubscribe-form-action.php#L39","https://plugins.trac.wordpress.org/browser/shapepress-dsgvo/tags/3.1.38/includes/class-sp-dsgvo-ajax-action.php#L69","https://plugins.trac.wordpress.org/changeset?old_path=/shapepress-dsgvo/tags/3.1.38&new_path=/shapepress-dsgvo/tags/3.1.39"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4283.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4283","state":"PUBLISHED","datePublished":"2026-03-24T04:27:50.054Z","dateUpdated":"2026-04-08T16:41:24.691Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-16T16:17:14.969Z"},"containers":{"cna":{"title":"WP DSGVO Tools (GDPR) <= 3.1.38 - Missing Authorization to Unauthenticated Account Destruction of Non-Admin Users","descriptions":[{"lang":"en","value":"The WP DSGVO Tools (GDPR) plugin for WordPress is vulnerable to unauthorized account destruction in all versions up to, and including, 3.1.38.
