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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":9.1},"cwes":["CWE-287"],"references":["https://github.com/vendurehq/vendure/commit/3bb04718ea4f9395fda731bd2a4bcfc3afb0a485","https://github.com/vendurehq/vendure/releases/tag/v3.7.0","https://github.com/vendurehq/vendure/security/advisories/GHSA-6j36-r6pr-59x4","https://github.com/vendurehq/vendure/security/advisories/GHSA-6j36-r6pr-59x4"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-63472","score":0.00589,"percentile":0.48195,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-6j36-r6pr-59x4","url":"https://osv.dev/vulnerability/GHSA-6j36-r6pr-59x4","summary":"Vendure affected by external-authentication account takeover: external login linked to a pre-existing account by email without verification","modified":"2026-09-17T15:00:06.681857527Z","packages":[{"ecosystem":"npm","name":"@vendure/core","purl":"pkg:npm/%40vendure/core","ranges":["<3.7.0"],"fixed":["3.7.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
