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."}],"title":"WP DSGVO Tools (GDPR) <= 3.1.38 - Missing Authorization to Unauthenticated Account Destruction of Non-Admin Users","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/21389122-cb39-45d1-a889-b830d3a55603?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/shapepress-dsgvo/tags/3.1.38/public/shortcodes/super-unsubscribe/unsubscribe-form-action.php#L39"},{"url":"https://plugins.trac.wordpress.org/browser/shapepress-dsgvo/tags/3.1.38/includes/models/unsubscriber.php#L24"},{"url":"https://plugins.trac.wordpress.org/browser/shapepress-dsgvo/tags/3.1.38/includes/class-sp-dsgvo-data-collecter.php#L250"},{"url":"https://plugins.trac.wordpress.org/browser/shapepress-dsgvo/trunk/public/shortcodes/super-unsubscribe/unsubscribe-form-action.php#L39"},{"url":"https://plugins.trac.wordpress.org/browser/shapepress-dsgvo/tags/3.1.38/includes/class-sp-dsgvo-ajax-action.php#L69"},{"url":"https://plugins.trac.wordpress.org/changeset?old_path=/shapepress-dsgvo/tags/3.1.38&new_path=/shapepress-dsgvo/tags/3.1.39"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-862 Missing Authorization","cweId":"CWE-862","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","baseScore":9.1,"baseSeverity":"CRITICAL"}}],"credits":[{"lang":"en","type":"finder","value":"Angus Girvan"}],"timeline":[{"time":"2026-03-16T19:16:29.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-03-23T16:27:36.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-24T13:18:37.216159Z","id":"CVE-2026-4283","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-03-24T13:18:49.435Z"}}]}}
