Prior to 1.4.1, node-forge parsed deprecated extension OIDs 2.5.29.10 and 2.5.29.13 as basicConstraints, and pki.verifyCertificateChain() used the first extension with that name. Exploitation requires a CA trusted by the application to issue a certificate carrying an attacker-supplied deprecated-OID extension, commonly because the CA copies extensions from a certificate signing request. By placing a permissive deprecated extension before the genuine 2.5.29.19 basicConstraints extension, the certificate holder could have the certificate accepted as a CA and issue certificates for arbitrary names, enabling server or client impersonation. If the issuing CA adds a keyUsage extension without keyCertSign, node-forge rejects the chain. This issue is fixed in version 1.4.1."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"digitalbazaar","product":"forge","versions":[{"version":"< 1.4.1","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","baseScore":7.4,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":2.2,"impactScore":5.2}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-29T20:24:38.825329Z","id":"CVE-2026-119190","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-295"},{"lang":"en","value":"CWE-436"}]}],"references":[{"url":"https://github.com/digitalbazaar/forge/commit/58c06bc251856b409c30ecb35a93f5f6c9bbc84a","source":"security-advisories@github.com"},{"url":"https://github.com/digitalbazaar/forge/releases/tag/v1.4.1","source":"security-advisories@github.com"},{"url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-5x38-2vff-x55p","source":"security-advisories@github.com"},{"url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-5x38-2vff-x55p","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}
