This is due to the `express_pay_product_page_pay_for_order()` function logging users in based solely on a user-supplied billing email address during guest checkout for subscription products, without verifying email ownership, requiring a password, or validating a one-time token. This makes it possible for unauthenticated attackers to log in as any existing user, including administrators, by providing the target user's email address in the billing_details parameter, resulting in complete account takeover and site compromise."}],"title":"Visa Acceptance Solutions <= 2.1.0 - Unauthenticated Authentication Bypass via Billing Email","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/8d3aea10-d7a0-44bd-94dc-3bad0d27dbd8?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/visa-acceptance-solutions/tags/2.1.0/public/class-visa-acceptance-payment-gateway-expresspay-public.php#L777"},{"url":"https://plugins.trac.wordpress.org/browser/visa-acceptance-solutions/tags/2.1.0/public/class-visa-acceptance-payment-gateway-expresspay-public.php#L790"},{"url":"https://plugins.trac.wordpress.org/browser/visa-acceptance-solutions/trunk/public/class-visa-acceptance-payment-gateway-expresspay-public.php#L777"},{"url":"https://plugins.trac.wordpress.org/browser/visa-acceptance-solutions/trunk/public/class-visa-acceptance-payment-gateway-expresspay-public.php#L790"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-288 Authentication Bypass Using an Alternate Path or Channel","cweId":"CWE-288","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL"}}],"credits":[{"lang":"en","type":"finder","value":"Jude Nwadinobi"}],"timeline":[{"time":"2026-04-14T19:51:38.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-15T15:49:47.269418Z","id":"CVE-2026-3461","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-15T15:50:14.969Z"}}]}}
