A certificate containing `DNS:127.0.0.1` and no `IP Address:127.0.0.1` SAN was therefore accepted, while the same certificate is correctly rejected for `127.0.0.1`. Exploitation requires a certificate with a numeric DNS SAN issued by a CA trusted by the client, and a platform resolver that accepts these spellings, such as glibc.\n\nThis vulnerability affects Node.js **26.x**, **24.x**, and **22.x**."}],"affected":[{"source":"support@hackerone.com","affectedData":[{"vendor":"nodejs","product":"node","defaultStatus":"unaffected","versions":[{"version":"22.23.3","lessThanOrEqual":"22.23.3","versionType":"semver","status":"affected"},{"version":"24.22.0","lessThanOrEqual":"24.22.0","versionType":"semver","status":"affected"},{"version":"26.12.0","lessThanOrEqual":"26.12.0","versionType":"semver","status":"affected"}]}]}],"metrics":{"cvssMetricV30":[{"source":"support@hackerone.com","type":"Secondary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:L","baseScore":6.7,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"LOW"},"exploitabilityScore":1.2,"impactScore":5.5}]},"weaknesses":[{"source":"support@hackerone.com","type":"Secondary","description":[{"lang":"en","value":"CWE-295"}]}],"references":[{"url":"https://nodejs.org/en/blog/vulnerability/october-2026-security-releases","source":"support@hackerone.com"}]}}]}
