Routine

MEDIUM 6.1UPGRADE

CVE-2025-5062 is a medium-severity flaw (CVSS 6.1) affecting woocommerce. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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.

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.
