{"id":"CVE-2026-63472","state":"PUBLISHED","title":"Vendure: External-authentication account takeover: external login linked to a pre-existing account by email without verification","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.","publishedAt":"2026-09-17T14:40:31.353Z","updatedAt":"2026-09-17T15:21:11.192Z","severity":{"score":9.1,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["vendurehq vendure"],"affected":[{"vendor":"vendurehq","product":"vendure","versions":[{"version":"< 3.7.0","status":"affected"}]}],"references":["https://github.com/vendurehq/vendure/security/advisories/GHSA-6j36-r6pr-59x4","https://github.com/vendurehq/vendure/commit/3bb04718ea4f9395fda731bd2a4bcfc3afb0a485","https://github.com/vendurehq/vendure/releases/tag/v3.7.0"],"weaknesses":["CWE-287"],"ingestedAt":"2026-10-29T20:12:41.951Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/63xxx/CVE-2026-63472.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-63472","state":"PUBLISHED","datePublished":"2026-09-17T14:40:31.353Z","dateUpdated":"2026-09-17T15:21:11.192Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-16T21:37:45.769Z"},"containers":{"cna":{"title":"Vendure: External-authentication account takeover: external login linked to a pre-existing account by email without verification","descriptions":[{"lang":"en","value":"Vendure is an open-source headless commerce platform.
