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

9.1
Missing Authorization
CVE CVE-2026-4283
CVSS 9.1 (Critical)
Publicly Published March 23, 2026

Researcher shark3y

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.
