Summary
The Hyyan WooCommerce Polylang Integration plugin for WordPress through 1.5.0 is affected by SQL injection (CWE-89) via the 'variation_ids' parameter of the 'woocommerce_remove_variations' AJAX action. Insufficient escaping and preparation of an existing SQL query let an authenticated attacker with Subscriber-level access or above append SQL queries to existing ones. The attacker can use this to extract sensitive information from the database.

Description from the CNA
The Hyyan WooCommerce Polylang Integration plugin for WordPress is vulnerable to SQL Injection via the 'variation_ids' parameter of the 'woocommerce_remove_variations' AJAX action in versions up to, and including, 1.5.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
