Contact Form by Supsystic < 1.11.1 - Arbitrary Plugin Settings Update via CSRF

Published Oct 29, 2026 CVSS 3.1 · 5.4 Medium EPSS < 1% KEV · Not listed
Description
The Contact Form by Supsystic WordPress plugin before 1.11.1 does not verify a CSRF nonce before saving its mail settings, allowing an attacker to overwrite the site's outbound mail configuration, including the SMTP server, its credentials and the notification recipient, by tricking a logged-in administrator into visiting a crafted page, which can route the Contact Form by Supsystic WordPress plugin before 1.11.1's contact-form notifications through infrastructure the attacker controls.
