- CVE-2026-1305, 27 Feb 2026
- The Japanized for WooCommerce plugin for WordPress is vulnerable to Improper Authentication in versions up to, and including, 2.8.4. This is due to a flawed permission check in the `paidy_webhook_permission_check` function that unconditionally returns `true` when the webhook signature header is omitted. This makes it possible for unauthenticated attackers to bypass payment verification and fraudulently mark orders as "Processing" or "Completed" without actual payment via a crafted POST request to the Paidy webhook endpoint. CVE record
- CVE-2025-14886, 9 Jan 2026
- The Japanized for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `order` REST API endpoint in all versions up to, and including, 2.7.17. This makes it possible for unauthenticated attackers to mark any WooCommerce order as processed/completed. CVE record
- CVE-2023-0948, 8 May 2023
- The Japanized For WooCommerce WordPress plugin before 2.5.8 does not escape generated URLs before outputting them in attributes, leading to Reflected Cross-Site Scripting CVE record
- CVE-2023-0942, 21 Feb 2023
- The Japanized For WooCommerce plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘tab’ parameter in versions up to, and including, 2.5.4 due to insufficient input sanitization and output escaping. 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.
