{"id":"CVE-2026-1305","state":"PUBLISHED","title":"Japanized for WooCommerce <= 2.8.4 - Missing Authorization to Unauthenticated Paidy Order Manipulation","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.","publishedAt":"2026-02-27T09:23:43.326Z","updatedAt":"2026-04-08T17:06:07.194Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["shoheitanaka Japanized for WooCommerce"],"affected":[{"vendor":"shoheitanaka","product":"Japanized for WooCommerce","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.8.4","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/8cef4b2b-ae8d-4e18-b763-6960a0b944f7?source=cve","https://plugins.trac.wordpress.org/browser/woocommerce-for-japan/trunk/includes/gateways/paidy/class-wc-paidy-endpoint.php#L63","https://plugins.trac.wordpress.org/browser/woocommerce-for-japan/trunk/includes/gateways/paidy/class-wc-paidy-endpoint.php#L108","https://plugins.trac.wordpress.org/browser/woocommerce-for-japan/tags/2.8.2/includes/gateways/paidy/class-wc-paidy-endpoint.php#L108","https://plugins.trac.wordpress.org/browser/woocommerce-for-japan/tags/2.8.2/includes/gateways/paidy/class-wc-paidy-endpoint.php#L63","https://plugins.trac.wordpress.org/changeset/3464868/woocommerce-for-japan/trunk/includes/gateways/paidy/class-wc-paidy-endpoint.php"],"weaknesses":["CWE-287"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1305.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1305","state":"PUBLISHED","datePublished":"2026-02-27T09:23:43.326Z","dateUpdated":"2026-04-08T17:06:07.194Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-21T19:03:56.817Z"},"containers":{"cna":{"title":"Japanized for WooCommerce <= 2.8.4 - Missing Authorization to Unauthenticated Paidy Order Manipulation","descriptions":[{"lang":"en","value":"The Japanized for WooCommerce plugin for WordPress is vulnerable to Improper Authentication in versions up to, and including, 2.8.4.
