At a glance

CVE-2024-3665 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Rank Math SEO WordPress plugin, affecting versions <= 1.0.216. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 1.0.217; sites on affected versions should update now. Disclosed April 2024, reported by wesley (wcraft).

Vulnerability Overview

The Rank Math SEO with AI SEO Tools plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's HowTo and FAQ widgets in all versions up to, and including, 1.0.216 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

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 interaction from a victim user.

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

Reaching this weakness in Rank Math SEO <= 1.0.216 takes an account at Contributor level or above. 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 Rank Math SEO the fix is 1.0.217: builds <= 1.0.216 are affected, anything from 1.0.217 onward is not.

Remediation

Update to version 1.0.217, or a newer patched version

How does WordSec protect against this?

An attacker needs Contributor access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Rank Math SEO 1.0.217 closes this, and updating the plugin is the step that ends it.
