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.

AI Analysis

Impact

The WP DSGVO Tools (GDPR) plugin allows an unauthenticated user to trigger the super-unsubscribe AJAX action with the process_now parameter, bypassing the intended email confirmation. This action immediately anonymizes and deletes any non-administrator user account, overwriting usernames, emails, roles, and usermeta, and removing associated comments. The result is an irreversible loss of user data and disruption of legitimate user access without any prior authorization.

Affected Systems

Customers running the WP DSGVO Tools (GDPR) WordPress plugin from vendor legalweb, in any version up to and including 3.1.38, are affected. The vulnerability exists in all earlier releases of the plugin as well.

Risk and Exploitability

The CVSS base score of 9.1 marks this as critical, and while the EPSS score is not available, the lack of authentication requirement and the public availability of the nonce on any page featuring the unsubscribe shortcode make exploitation trivially achievable through a simple HTTP request. The vulnerability is not listed in the CISA KEV catalog, but the potential for mass account deletions poses a significant business risk.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update the WP DSGVO Tools (GDPR) plugin to version 3.1.39 or later to remove the vulnerable super-unsubscribe action.
  • If an immediate update is not possible, temporarily remove or disable pages that use the [unsubscribe_form] shortcode to block public nonce exposure.
  • Consider disabling the super-unsubscribe AJAX endpoint or restricting it to authenticated users via custom code or a WordPress security plugin.
  • Audit user roles to ensure that sensitive accounts are protected and consider implementing additional role‑based restrictions around the plugin functionality.
