Oct 25, 2026Contact Form by Supsystic: Does not sanitise and escape a form nameCVE-2025-15705 · fixed in 1.8.0 · reported by WPScanLow 3.5
The Contact Form by Supsystic WordPress plugin before 1.8.0 does not sanitise and escape a form name, allowing users with access to the form editor to inject arbitrary web scripts that execute when another user views the form.

Sep 5, 2026Contact Form by Supsystic: Stored Cross-Site ScriptingCVE-2026-83625 · affects up to 1.10.2 · reported by WordfenceHigh 7.2
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.

Mar 30, 2026Contact Form by Supsystic: Server-Side Template Injection (SSTI) leading to Remote Code Execution (RCE)CVE-2026-4257 · affects up to 1.7.36 · reported by WordfenceCritical 9.8
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.
