CVE-2026-115299 · Contact Form by Supsystic < 1.11.1 - Arbitrary Plugin Settings Update via CSRF

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
