CVE-2026-1305 – Japanized for WooCommerce

CVE ID : CVE-2026-1305

Published : Feb. 27, 2026, 10:16 a.m. | 55 minutes ago

Description : 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.

Severity: 5.3 | MEDIUM
