{"id":"CVE-2026-63472","published":"2026-09-17T15:16:49.743","lastModified":"2026-09-17T21:16:02.560","description":"Vendure is an open-source headless commerce platform. Prior to 3.7.0, ExternalAuthenticationService.createCustomerAndUser in packages/core/src/service/helpers/external-authentication/external-authentication.service.ts selects an existing customer user by emailAddress and attaches a newly presented ExternalAuthenticationMethod without requiring verified to be true. In deployments with a custom external AuthenticationStrategy that forwards an email whose ownership the provider has not verified, an attacker can authenticate with a victim's email and bind the attacker's external identity to the victim's existing account. This can expose orders, addresses, and personal information and permit account changes or orders as the victim. Native-only email and password deployments and external strategies that always require provider-verified email ownership are unaffected, and new-account creation for an unused email remains permitted. This issue is fixed in version 3.7.0.","cvssScore":9.1,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","cwes":["CWE-287"],"vendors":[],"products":[],"references":[{"url":"https://github.com/vendurehq/vendure/commit/3bb04718ea4f9395fda731bd2a4bcfc3afb0a485","tags":[]},{"url":"https://github.com/vendurehq/vendure/releases/tag/v3.7.0","tags":[]},{"url":"https://github.com/vendurehq/vendure/security/advisories/GHSA-6j36-r6pr-59x4","tags":[]},{"url":"https://github.com/vendurehq/vendure/security/advisories/GHSA-6j36-r6pr-59x4","tags":[]}],"exploitRefs":[{"url":"https://github.com/vendurehq/vendure/commit/3bb04718ea4f9395fda731bd2a4bcfc3afb0a485","tags":[]},{"url":"https://github.com/vendurehq/vendure/releases/tag/v3.7.0","tags":[]},{"url":"https://github.com/vendurehq/vendure/security/advisories/GHSA-6j36-r6pr-59x4","tags":[]},{"url":"https://github.com/vendurehq/vendure/security/advisories/GHSA-6j36-r6pr-59x4","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows an attacker to authenticate with a victim's email and bind their external identity to the victim's account, exposing sensitive information and permitting account changes or orders as the victim.","exploitability":"Exploitation is relatively straightforward if the attacker can control the email being forwarded, as no verified ownership is required.","blast_radius":"If exploited, this can lead to significant exposure of the victim's personal information and account control, impacting their orders and addresses.","remediation":"Upgrade to version 3.7.0 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["auth-bypass","email","commerce"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-28T09:07:07.684Z"}}
