Joomla Extension - joomlart.com - Open mail relay via contact AJAX endpoint in T4 Page Builder extension < 2.3.0 - The front-end JSON editor endpoint exposes an action called contact that requires no authentication, no CSRF token, no captcha (when no captcha plugin is enabled) and has no rate limiting. The attacker fully controls the recipient, subject and HTML body, and the mail is sent from the site's configured sender identity (mailfrom/fromname).
