CVE-2026-115299 Details
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.
A Cross-Site Request Forgery (CSRF) vulnerability has been identified in the Contact Form by Supsystic WordPress plugin, affecting versions prior to 1.11.1. The vulnerability arises because the plugin does not validate a CSRF nonce before saving mail settings. This oversight allows an attacker to manipulate the site's outbound mail configuration, including the SMTP server, credentials, and notification recipient. Exploitation involves tricking a logged-in administrator into visiting a crafted page, which can redirect the plugin's contact-form notifications through the attacker's controlled infrastructure.
Users are advised to update the Contact Form by Supsystic WordPress plugin to version 1.11.1 or later.
