CVE-2026-83625 2 Supsysticcom, Wordpress 2 Contact Form By Supsystic, Wordpress 2026-09-05 7.2 High
The Contact Form by Supsystic plugin for WordPress is vulnerable to Stored Cross-Site Scripting via IP Address Header in all versions up to, and including, 1.10.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. An unauthenticated attacker can first call the 'updateNonce' action — which is accessible without authentication due to its absence from the plugin's permission list — to obtain a valid nonce, then submit a contact form with a malicious payload in a spoofed IP header such as X-Forwarded-For.
CVE-2026-73378 2 Supsysticcom, Wordpress 2 Contact Form By Supsystic, Wordpress 2026-08-24 7.1 High
Unauthenticated Cross Site Scripting (XSS) in Contact Form by Supsystic < 1.10.0 versions.
CVE-2026-73379 2 Supsysticcom, Wordpress 2 Contact Form By Supsystic, Wordpress 2026-08-24 6.5 Medium
Unauthenticated Bypass Vulnerability in Contact Form by Supsystic < 1.10.0 versions.
CVE-2026-4257 2 Supsysticcom, Wordpress 2 Contact Form By Supsystic, Wordpress 2026-04-24 9.8 Critical
The Contact Form by Supsystic plugin for WordPress is vulnerable to Server-Side Template Injection (SSTI) leading to Remote Code Execution (RCE) in all versions up to, and including, 1.7.36. This is due to the plugin using the Twig `Twig_Loader_String` template engine without sandboxing, combined with the `cfsPreFill` prefill functionality that allows unauthenticated users to inject arbitrary Twig expressions into form field values via GET parameters. This makes it possible for unauthenticated attackers to execute arbitrary PHP functions and OS commands on the server by leveraging Twig's `registerUndefinedFilterCallback()` method to register arbitrary PHP callbacks.
