What the vulnerability does
The WooCommerce Multilingual & Multicurrency with WPML plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg without appropriate escaping on the URL in all versions up to, and including, 5.3.7. 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
WPML Multilingual & Multicurrency for WooCommerce versions up to 5.3.7 contain a cross-site scripting (XSS) vulnerability. An attacker can inject malicious scripts that execute in the browsers of site visitors. The vulnerability requires user interaction—typically clicking a malicious link—and can affect other users or administrators on the site. Update to a version newer than 5.3.7 to remediate.
What an attacker can do
Inject malicious scripts that run in visitors' browsers, potentially stealing session tokens or redirecting users.
Potential impact on your site
Visitors and staff may have their sessions hijacked or be redirected to phishing sites; site reputation at risk.
Conditions required to exploit
No authentication required. Victim must click a malicious link or visit an attacker-controlled page.
