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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"vendurehq","product":"vendure","versions":[{"version":"< 3.7.0","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","baseScore":9.1,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":5.2}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-09-17T15:20:50.486756Z","id":"CVE-2026-63472","options":[{"exploitation":"poc"},{"automatable":"yes"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-287"}]}],"references":[{"url":"https://github.com/vendurehq/vendure/commit/3bb04718ea4f9395fda731bd2a4bcfc3afb0a485","source":"security-advisories@github.com"},{"url":"https://github.com/vendurehq/vendure/releases/tag/v3.7.0","source":"security-advisories@github.com"},{"url":"https://github.com/vendurehq/vendure/security/advisories/GHSA-6j36-r6pr-59x4","source":"security-advisories@github.com"},{"url":"https://github.com/vendurehq/vendure/security/advisories/GHSA-6j36-r6pr-59x4","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}
