CVE-2024-3519 is a medium-severity Improper Neutralization of Alternate XSS Syntax vulnerability in the Media Library Assistant WordPress plugin, affecting versions <= 3.15. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication.

Vulnerability Overview

The Media Library Assistant plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the lang parameter in all versions up to, and including, 3.15 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user 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-87: Improper Neutralization of Alternate XSS Syntax

The product does not neutralize or incorrectly neutralizes user-controlled input for alternate script syntax.

Remediation

Update to version 3.16, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Media Library Assistant: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Media Library Assistant 3.16 closes this, and updating the plugin is the step that ends it.
