Stored Cross-Site Scripting (XSS) Vulnerability in Marketing and SEO Booster Plugin

CVE-2024-9066

Summary

The Marketing and SEO Booster plugin for WordPress contains a vulnerability that allows authenticated users with Author-level access and above to perform Stored Cross-Site Scripting (XSS) attacks. This occurs due to a lack of adequate input sanitization and output escaping when handling SVG file uploads. When an attacker uploads a malicious SVG file, they can inject arbitrary JavaScript code that executes whenever users access the compromised SVG files. This vulnerability poses significant risks to the integrity of web applications, potentially leading to data theft, session hijacking, and other malicious activities.
