Q: Am I affected by this vulnerability?

You are affected if your site runs Woocommerce Multilingual.

Q: How do I fix it?

Update Woocommerce Multilingual to the latest available version. Where the vendor has not yet published a fix, remove or disable the plugin until they do. Until you can update, Request / payload inspection (WAF) in Hack Halt ProSecure contains this class of attack at the request layer.

Q: What can an attacker actually do?

This is a SQL Injection flaw. An attacker who exploits it can read, alter or delete anything in the site database, including user accounts and password hashes.

CVE-2026-120563

Vulnerability CVE-2026-120563 PLUGIN woocommerce-multilingual MEDIUM

The WooCommerce Multilingual & Multicurrency with WPML plugin for WordPress is vulnerable to SQL Injection in all versions up to, and including, 5.5.7. This is due to insufficient input validation on the currency exchange rate parameter in the save_currency() AJAX handler, which lacks capability checks and allows subscriber-level users to store malicious SQL payloads that are later concatenated directly into ORDER BY clauses without proper sanitization. This makes it possible for authenticated attackers, with Shop Manager-level access and above, to append additional SQL queries to extract sensitive information from the database.
