Detailsinfo A vulnerability was found in visaacceptancesolutions Visa Acceptance Solutions Plugin up to 2.1.0 on WordPress. It has been rated as critical. This issue affects the function express_pay_product_page_pay_for_order. The manipulation of the argument billing_details with an unknown input leads to a authentication bypass vulnerability. Using CWE to declare the problem leads to CWE-288. A product requires authentication, but the product has an alternate path or channel that does not require authentication. Impacted is confidentiality, integrity, and availability. The summary by CVE is: The Visa Acceptance Solutions plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 2.1.0. 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. The weakness was disclosed by Jude Nwadinobi. The advisory is shared at wordfence.com. The identification of this vulnerability is CVE-2026-3461 since 03/02/2026. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation.
