CVE-2024-39666 describes an Improper Neutralization of Input During Web Page Generation (XSS) vulnerability within the WooCommerce e-commerce plugin. This flaw allows attackers to inject malicious scripts into web pages, potentially leading to session hijacking, data theft, or defacement of the website. The vulnerability impacts WooCommerce versions 9.1.2 and earlier, and a patch is available in version 9.1.3.
The XSS vulnerability in WooCommerce allows an attacker to inject arbitrary JavaScript code into a user's browser when they visit a vulnerable page. This can be exploited to steal cookies, redirect users to malicious websites, or even execute arbitrary code on the user's machine if they have sufficient privileges. The impact is particularly severe for e-commerce sites, as attackers could target customer accounts to steal payment information or manipulate orders. A successful attack could also damage the site's reputation and erode customer trust. The blast radius extends to all users who interact with the vulnerable WooCommerce pages.
CVE-2024-39666 was publicly disclosed on August 18, 2024. There is currently no indication of active exploitation in the wild, but the availability of a public XSS vulnerability increases the risk of future attacks. The vulnerability is not currently listed on the CISA KEV catalog. Public proof-of-concept exploits are likely to emerge as the vulnerability gains more attention.

The primary mitigation for CVE-2024-39666 is to immediately upgrade WooCommerce to version 9.1.3 or later. If upgrading is not immediately feasible, consider implementing stricter input validation and output encoding on all user-supplied data displayed on the website. Web Application Firewalls (WAFs) can be configured to filter out potentially malicious JavaScript code. Regularly review and update WordPress and WooCommerce plugins to ensure they are patched against known vulnerabilities. After upgrading, confirm the fix by attempting to inject a simple XSS payload into a vulnerable field and verifying that it is properly sanitized.
Update the WooCommerce plugin to the latest available version. The Cross-Site Scripting (XSS) vulnerability has been fixed in versions later than 9.1.2. To update, go to the WordPress admin panel, then to the 'Plugins' section and look for WooCommerce. Click 'Update now' if a newer version is available.
