CVE-2026-83625 (GCVE-0-2026-83625)

Vulnerability from nvd – Published: 2026-09-05 07:38 – Updated: 2026-09-07 11:17

Title

Contact Form by Supsystic <= 1.10.2 - Unauthenticated Stored Cross-Site Scripting via IP Address Header

Summary

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.

Severity

7.2 (High)

CVE-2026-4257 (GCVE-0-2026-4257)

Vulnerability from nvd – Published: 2026-03-30 21:26 – Updated: 2026-04-08 16:48

Title

Contact Form by Supsystic <= 1.7.36 - Unauthenticated Server-Side Template Injection via Prefill Functionality

Summary

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.

Severity

9.8 (Critical)

CVE-2024-13452 (GCVE-0-2024-13452)

Vulnerability from nvd – Published: 2025-04-16 02:12 – Updated: 2026-04-08 17:16

Title

Contact Form by Supsystic <= 1.7.29 - Cross-Site Request Forgery to Stored Cross-Site Scripting via saveAsCopy AJAX Action

Summary

The Contact Form by Supsystic plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.7.29. This is due to missing or incorrect nonce validation on a saveAsCopy function. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Severity

6.1 (Medium)

Vulnerability from nvd – Published: 2023-05-16 23:35 – Updated: 2026-04-08 16:38

Title

Contact Form by Supsystic <= 1.7.24 - Cross-Site Request Forgery via AJAX action

Summary

The Contact Form by Supsystic plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.7.24. This is due to missing or incorrect nonce validation on the AJAX action handler. This makes it possible for unauthenticated attackers to execute AJAX actions via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

CVE-2026-83625 (GCVE-0-2026-83625)

Vulnerability from cvelistv5 – Published: 2026-09-05 07:38 – Updated: 2026-09-07 11:17

Title

Contact Form by Supsystic <= 1.10.2 - Unauthenticated Stored Cross-Site Scripting via IP Address Header

Summary

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.

Severity

7.2 (High)

CVE-2026-4257 (GCVE-0-2026-4257)

Vulnerability from cvelistv5 – Published: 2026-03-30 21:26 – Updated: 2026-04-08 16:48

Title

Contact Form by Supsystic <= 1.7.36 - Unauthenticated Server-Side Template Injection via Prefill Functionality

Summary

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.

Severity

9.8 (Critical)

CVE-2024-13452 (GCVE-0-2024-13452)

Vulnerability from cvelistv5 – Published: 2025-04-16 02:12 – Updated: 2026-04-08 17:16

Title

Contact Form by Supsystic <= 1.7.29 - Cross-Site Request Forgery to Stored Cross-Site Scripting via saveAsCopy AJAX Action

Summary

The Contact Form by Supsystic plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.7.29. This is due to missing or incorrect nonce validation on a saveAsCopy function. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Severity
