At a glance

CVE-2024-11813 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Pulsating Chat Button WordPress plugin, affecting versions <= 1.4.1. 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 1.4.2; sites on affected versions should update now. Disclosed December 2024, reported by SOPROBRO.

Vulnerability Overview

The Pulsating Chat Button plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4.1. This is due to missing or incorrect nonce validation on the amin_chat_button_settings_page() 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-352: Cross-Site Request Forgery (CSRF)

Pulsating Chat Button <= 1.4.1 carries this weakness at amin_chat_button_settings_page(), and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Pulsating Chat Button the fix is 1.4.2: builds <= 1.4.1 are affected, anything from 1.4.2 onward is not.

Remediation

Update to version 1.4.2, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Pulsating Chat Button: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Pulsating Chat Button 1.4.2 closes this, and updating the plugin is the step that ends it.
