The plugin registers a REST API webhook endpoint at /wp-json/strabl/webhook/order with a permission_callback of __return_true, which allows all incoming requests without any authentication or authorization checks. No shared secret, signature validation, HMAC verification, or token-based authentication is implemented. This makes it possible for unauthenticated attackers to create fraudulent WooCommerce orders and mark them as completed by supplying paymentStatus=paid, manipulate existing order statuses by providing an externalOrderId, create new WordPress user accounts with the customer role, issue refunds on existing orders, cancel existing orders, and apply chargeback fees — all without making a legitimate payment or having any valid credentials."}],"title":"STRABL <= 4.5 - Unauthenticated Arbitrary Webhook Creation via REST API Endpoint","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/04eb82e4-1738-44c7-980e-8e33a7a3a23a?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/strabl-a-checkout-solution/trunk/src/Orders/OrderWebhookController.php#L60"},{"url":"https://plugins.trac.wordpress.org/browser/strabl-a-checkout-solution/tags/4.5/src/Orders/OrderWebhookController.php#L60"},{"url":"https://plugins.trac.wordpress.org/browser/strabl-a-checkout-solution/trunk/src/Orders/OrderWebhookController.php#L64"},{"url":"https://plugins.trac.wordpress.org/browser/strabl-a-checkout-solution/tags/4.5/src/Orders/OrderWebhookController.php#L64"},{"url":"https://plugins.trac.wordpress.org/browser/strabl-a-checkout-solution/trunk/src/Orders/OrderWebhookController.php#L88"},{"url":"https://plugins.trac.wordpress.org/browser/strabl-a-checkout-solution/tags/4.5/src/Orders/OrderWebhookController.php#L88"},{"url":"https://plugins.trac.wordpress.org/browser/strabl-a-checkout-solution/trunk/src/Orders/OrderWebhookController.php#L550"},{"url":"https://plugins.trac.wordpress.org/browser/strabl-a-checkout-solution/tags/4.5/src/Orders/OrderWebhookController.php#L550"},{"url":"https://plugins.trac.wordpress.org/browser/strabl-a-checkout-solution/trunk/src/Orders/OrderWebhookController.php#L199"},{"url":"https://plugins.trac.wordpress.org/browser/strabl-a-checkout-solution/tags/4.5/src/Orders/OrderWebhookController.php#L199"},{"url":"https://plugins.trac.wordpress.org/browser/strabl-a-checkout-solution/trunk/src/Orders/CustomerRepository.php#L17"},{"url":"https://plugins.trac.wordpress.org/browser/strabl-a-checkout-solution/tags/4.5/src/Orders/CustomerRepository.php#L17"},{"url":"https://plugins.trac.wordpress.org/changeset/3558301"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-862 Missing Authorization","cweId":"CWE-862","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":"Teerachai Somprasong"}],"timeline":[{"time":"2026-03-09T10:17:59.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-06-18T17:50:04.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-06-22T15:59:15.746377Z","id":"CVE-2026-3640","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":"2026-06-22T15:59:26.286Z"}}]}}
