CVE-2026-4283— WordPress plugin WP DSGVO Tools (GDPR) 安全漏洞

WP DSGVO Tools (GDPR) <= 3.1.38 - Missing Authorization to Unauthenticated Account Destruction of Non-Admin Users

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.
