What the vulnerability does
The WooCommerce plugin for WordPress is vulnerable to PostMessage-Based Cross-Site Scripting via the 'customize-store' page in all versions up to, and including, 9.4.2 due to insufficient input sanitization and output escaping on PostMessage data. 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.
Explanation of Vulnerability in Simple Terms
WooCommerce versions up to 9.3.2 contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts into pages viewed by other users. The vulnerability requires user interaction—typically clicking a malicious link—and can affect the integrity and confidentiality of user data. Sites should update to version 10.9.1 or later.
What an attacker can do
Inject malicious scripts that execute in other users' browsers when they visit a crafted link.
Potential impact on your site
Attackers can steal user session tokens, modify page content, or redirect visitors to phishing sites.
Conditions required to exploit
No authentication required. Victim must click a malicious link or visit an attacker-controlled page.
