Prior to 1.4.1, the affected implementation used pki.verifyCertificateChain(), pki.createCaStore(), duplicate subject names to process the relevant input or security decision. node-forge modified the CA store while trying certificates that shared a subject name during pki.verifyCertificateChain(). A failed chain verification could permanently remove trusted CA certificates from the store, causing later valid chains to fail and creating a persistent availability impact for applications that reused the store. This issue is fixed in version 1.4.1.","epss":{"date":"2026-11-03","percentile":0.06632,"score":0.00172},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-4487-j8r4-4g2f"}],"kev":null,"metrics":[{"score":3.7,"severity":"low","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"}],"modifiedAt":1793756224842,"publishedAt":1793299655961,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-4487-j8r4-4g2f"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/digitalbazaar/forge/commit/f6555609bd30f442fbfacd543155928ceccf98d0"},{"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-4487-j8r4-4g2f"},{"source":"OSV / GitHub Security Advisories","tags":["advisory"],"url":"https://github.com/advisories/GHSA-4487-j8r4-4g2f"},{"source":"OSV / GitHub Security Advisories","tags":["osv"],"url":"https://osv.dev/vulnerability/GHSA-4487-j8r4-4g2f"}],"remediation":[{"kind":"fix","source":"OSV GHSA-4487-j8r4-4g2f","text":"node-forge (npm): OSV reports a fixed version 1.4.1.
