The WooCommerce plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in all versions before 8.4.0 due to insufficient input sanitization and output escaping.

This issue was patched in version 8.4.0 and only affects versions up to 8.3.0. Please rest assured knowing you can update the plugin to version 8.4.0 and this issue will be patched.
