WordPress vulnerability analysis and mitigation

Overview

CVE-2022-4481 is a Stored Cross-Site Scripting (XSS) vulnerability discovered in the Mesmerize Companion WordPress plugin versions 1.6.134 and below. The vulnerability was publicly disclosed on December 20, 2022, affecting websites using the Mesmerize theme along with the companion plugin (WPScan).

Technical details

The vulnerability stems from improper validation and escaping of shortcode attributes before they are output back to the page. This security flaw allows users with contributor-level permissions or higher to inject malicious JavaScript code through shortcode attributes. The vulnerability has been assigned a CVSS score of 6.8 (medium severity) and is classified under CWE-79 (WPScan).

Impact

When exploited, this vulnerability allows attackers with contributor-level access to perform Stored Cross-Site Scripting attacks that could target high-privilege users such as administrators. The stored nature of the XSS makes it particularly dangerous as the malicious code persists on the website and executes whenever a targeted user views the affected page (WPScan).

Mitigation and workarounds

The vulnerability has been patched in version 1.6.135 of the Mesmerize Companion plugin. Website administrators are strongly advised to update to this version or later to protect against potential XSS attacks (WPScan).
