{"cve":"CVE-2026-4283","nvd":{"published":"2026-03-24T05:16:24.343","modified":"2026-06-17T10:56:21.483","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","score":9.1},"cwes":["CWE-862"],"references":["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/browser/shapepress-dsgvo/tags/3.1.38/includes/class-sp-dsgvo-data-collecter.php#L250","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/public/shortcodes/super-unsubscribe/unsubscribe-form-action.php#L39","https://plugins.trac.wordpress.org/browser/shapepress-dsgvo/trunk/public/shortcodes/super-unsubscribe/unsubscribe-form-action.php#L39"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-4283","score":0.00439,"percentile":0.38146,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
