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.","state":0,"publishedAt":"2026-10-29T19:25:09.677+00:00","modifiedAt":"2026-10-29T20:25:04.131+00:00","affected":[{"ecosystem":"Vendor product","name":"forge","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"digitalbazaar\",\n                    \"product\": \"forge\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.4.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","score":7.4,"severity":"HIGH"}],"references":["https://github.com/digitalbazaar/forge/security/advisories/GHSA-5x38-2vff-x55p","https://github.com/digitalbazaar/forge/commit/58c06bc251856b409c30ecb35a93f5f6c9bbc84a","https://github.com/digitalbazaar/forge/releases/tag/v1.4.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-119190","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-119190","identifiers":["CVE-2026-119190"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
