CVE-2023-5054Known exploitationNetwork attack vector

Unauthenticated email relay via directly accessible mail handler

Published Sep 19, 2023 · Updated Apr 8, 2026

Missing authorization in Super Store Finder 6.9.3 and earlier allows remote attackers to relay arbitrary email through a WordPress site. The publicly reachable sendMail.php file processes attacker-controlled message content for delivery without an authorization gate. No account or user interaction is required; abuse sends arbitrary content from the vulnerable server but does not itself expose site data or grant site control.
