{"affected":[{"product":"forge","source":"CNA: GitHub_M","vendor":"digitalbazaar","versions":[{"status":"affected","version":"< 1.4.1"}]}],"cveId":"CVE-2026-119189","cwes":["CWE-295"],"description":"Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Prior to 1.4.1, node-forge enforced an X.509 CA certificate's basicConstraints.pathLenConstraint only when that certificate also carried a keyUsage extension. Exploitation requires a path-length-constrained CA without keyUsage that chains to a root trusted by the application, and an attacker who holds that CA's private key or obtains a subordinate CA certificate from it. The attacker could then construct a chain exceeding the declared path length that still passed pki.verifyCertificateChain(). Public web PKI CA certificates normally include keyUsage; private PKIs with CA certificates created without it are more likely to be affected. This issue is fixed in version 1.4.1.","epss":{"date":"2026-11-04","percentile":0.05813,"score":0.00165},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-h46v-rmh6-fq4f"}],"kev":null,"metrics":[{"score":5.9,"severity":"medium","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},{"score":5.9,"severity":"medium","source":"NVD: security-advisories@github.com","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"}],"modifiedAt":1793726283370,"publishedAt":1793301805238,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-h46v-rmh6-fq4f"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/digitalbazaar/forge/commit/696db92348623e88cc63c35f0a89ede481d55ad0"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/digitalbazaar/forge/releases/tag/v1.4.1"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-h46v-rmh6-fq4f"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/digitalbazaar/forge/commit/696db92348623e88cc63c35f0a89ede481d55ad0"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/digitalbazaar/forge/releases/tag/v1.4.1"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-h46v-rmh6-fq4f"},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":[],"url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-h46v-rmh6-fq4f"}],"remediation":[],"revision":"75c2f73dee3a40ceea8de736d08bccb289c6ffcf717e69ad72e5f3b88f297bd1","sources":[{"modifiedAt":1793722976742,"name":"CNA: GitHub_M","retrievedAt":1793725837194,"url":"https://www.cve.org/CVERecord?id=CVE-2026-119189"},{"modifiedAt":1793726283370,"name":"NVD","retrievedAt":1793729933817,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-119189"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793858224393,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-119189"}],"ssvc":{"assessedAt":1793722952681,"automatable":"no","exploitation":"poc","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Forge: X.509 pathLenConstraint not enforced by verifyCertificateChain() for CA certificates without keyUsage","updatedAt":1793858224393}
