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."}],"title":"Japanized for WooCommerce <= 2.8.4 - Missing Authorization to Unauthenticated Paidy Order Manipulation","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/8cef4b2b-ae8d-4e18-b763-6960a0b944f7?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/woocommerce-for-japan/trunk/includes/gateways/paidy/class-wc-paidy-endpoint.php#L63"},{"url":"https://plugins.trac.wordpress.org/browser/woocommerce-for-japan/trunk/includes/gateways/paidy/class-wc-paidy-endpoint.php#L108"},{"url":"https://plugins.trac.wordpress.org/browser/woocommerce-for-japan/tags/2.8.2/includes/gateways/paidy/class-wc-paidy-endpoint.php#L108"},{"url":"https://plugins.trac.wordpress.org/browser/woocommerce-for-japan/tags/2.8.2/includes/gateways/paidy/class-wc-paidy-endpoint.php#L63"},{"url":"https://plugins.trac.wordpress.org/changeset/3464868/woocommerce-for-japan/trunk/includes/gateways/paidy/class-wc-paidy-endpoint.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-287 Improper Authentication","cweId":"CWE-287","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","baseScore":5.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Osvaldo Noe Gonzalez Del Rio"}],"timeline":[{"time":"2026-01-21T19:19:12.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-02-26T21:04:26.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-02-27T15:39:13.780413Z","id":"CVE-2026-1305","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-02-27T15:39:31.362Z"}}]}}
