Contact-form modification via missing nonce validation
Published May 10, 2024 · Updated Apr 28, 2026
Cross-site request forgery in Kiboko Labs Arigato Autoresponder and Newsletter 2.7.2.3 and earlier allows remote attackers to alter contact forms. The contact_form() handler accepts state-changing requests without a valid WordPress nonce, so attacker-supplied form details are processed in an administrator session. Exploitation requires an administrator to interact with a crafted link or page; the demonstrated consequence is unauthorized modification of contact-form details.
