Prior to version 3.5.3, the `NativeAuthenticationStrategy.authenticate()` method is vulnerable to a timing attack that allows attackers to enumerate valid usernames (email addresses). In `packages/core/src/config/auth/native-authentication-strategy.ts`, the authenticate method returns immediately if a user is not found. The significant timing difference (~200-400ms for bcrypt vs ~1-5ms for DB miss) allows attackers to reliably distinguish between existing and non-existing accounts. Version 3.5.3 fixes the issue.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U","score":2.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-202"],"references":["https://github.com/vendurehq/vendure/releases/tag/v3.5.3","https://github.com/vendurehq/vendure/security/advisories/GHSA-6f65-4fv2-wwch"],"products":["vendure:vendure"],"source":"nvd","synced_at":"2026-10-19T22:22:27.261130201+00:00"},"epss":{"cve":"CVE-2026-25050","score":0.004,"percentile":0.34231,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-6f65-4fv2-wwch","url":"https://osv.dev/vulnerability/GHSA-6f65-4fv2-wwch","summary":"Vendure vulnerable to timing attack that enables user enumeration in NativeAuthenticationStrategy","modified":"2026-02-03T03:03:38.760480Z","packages":[{"ecosystem":"npm","name":"@vendure/core","purl":"pkg:npm/%40vendure/core","ranges":["<3.5.3"],"fixed":["3.5.3"]}]}],"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).
