At a glance

CVE-2024-13452 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Contact Form by Supsystic WordPress plugin, affecting versions <= 1.7.29. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.7.30; sites on affected versions should update now. Disclosed April 2025, reported by Tim Coen.

Vulnerability Overview

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.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Reaching this weakness in Contact Form by Supsystic <= 1.7.29 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Contact Form by Supsystic the fix is 1.7.30: builds <= 1.7.29 are affected, anything from 1.7.30 onward is not.

Remediation

Update to version 1.7.30, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Contact Form by Supsystic: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Contact Form by Supsystic 1.7.30 closes this, and updating the plugin is the step that ends it.
