Detection Guidance

This vulnerability affects WooCommerce POS Plugin versions 1.8.14 and below, allowing unauthenticated attackers to perform privileged actions due to missing authorization checks.

To detect if your system is vulnerable, first verify the installed WooCommerce POS plugin version. You can do this by checking the plugin version in the WordPress admin dashboard or by inspecting the plugin files directly.

From the command line, you can check the plugin version by running commands like:

• grep -i 'Version' wp-content/plugins/woocommerce-pos/readme.txt
• wp plugin list --status=active | grep woocommerce-pos

If the version is 1.8.14 or below, your system is vulnerable.

Additionally, monitoring network traffic for suspicious requests targeting WooCommerce POS endpoints without authentication could help detect exploitation attempts. However, specific detection commands or signatures are not provided.

Until you update to version 1.9.0 or later, applying mitigation rules from Patchstack to block attacks is recommended.
