CVE-2026-10034 | WP DSGVO Tools (GDPR) <= 3.1.39 - Missing Authorization to Unauthenticated Sensitive Personal Data Disclosure via subject-access-request AJAX Endpoint (process_now/is_ajax Parameters)

The WP DSGVO Tools (GDPR) plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.1.39. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to supply an arbitrary victim email address and trigger immediate SAR processing via the process_now and is_ajax parameters, receiving tokenized download links (zip_link, pdf_link) in the HTTP response that expose the victim's personal data — including WordPress account details, comment author names, email addresses, IP addresses, and comment content — without any proof of ownership. The nonce used for the CSRF check is publicly rendered by the SAR shortcode form and is shared across all anonymous visitors, meaning any unauthenticated attacker can trivially obtain a valid nonce and bypass this gate entirely.
