What is CVE-2026-4283?
CVE-2026-4283 is a critical missing authorization vulnerability in legalweb WP DSGVO Tools (GDPR), published on 24 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
Weakness: CWE-862
