Prior to 1.4.1, the affected implementation used certificate.verify(child), _verifySignature(), lib/x509.js to process the relevant input or security decision. node-forge selected RSA padding and RSASSA-PSS parameters from the issuer certificate rather than the child certificate being verified. A child labeled as RSASSA-PSS could therefore be accepted with a PKCS#1 v1.5 signature when the issuer used PKCS#1 v1.5. The signature still had to be produced with the trusted issuer's private key, so this did not permit certificate identity forgery, but it could bypass policies that require a declared signature scheme. This issue is fixed in version 1.4.1.","score":3.7,"severity":"low","published":"2026-10-29T18:33:46.399Z","modified":"2026-10-29T18:33:46.399Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"digitalbazaar","name":"forge","platforms":[],"versions":[{"version":"< 1.4.1","status":"affected"}],"cpes":[],"source":"GitHub_M","url":"https://www.cve.org/CVERecord?id=CVE-2026-118774"}],"remediation":[],"references":["https://github.com/digitalbazaar/forge/security/advisories/GHSA-9wg5-mj3p-v49q","https://github.com/digitalbazaar/forge/commit/c7f42614d5166a77ddf11ce174b2601b14f6956b","https://github.com/digitalbazaar/forge/releases/tag/v1.4.1"],"sources":[{"name":"CVE","id":"CVE-2026-118774","modified":"2026-10-29T18:33:46.399Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-118774"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N","score":3.7}],"sourceAffected":[],"observedAt":"2026-10-29T18:48:54.679Z","kev":{"status":"not-listed","checkedAt":"2026-10-30T22:50:31.153Z"},"coverage":[{"source":"NVD","status":"no-result","checkedAt":"2026-10-29T18:50:30.984Z","attemptedAt":"2026-10-29T18:50:30.984Z"},{"source":"GHSA","status":"no-result","checkedAt":"2026-10-29T18:50:30.987Z","attemptedAt":"2026-10-29T18:50:30.987Z"},{"source":"EUVD","status":"refresh-failed","attemptedAt":"2026-10-29T18:50:30.987Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-10-29T18:50:31.424Z","attemptedAt":"2026-10-29T18:50:31.424Z"}],"evidence":[],"aiSummary":{"text":"Forge, a JavaScript TLS implementation, had a weakness in certificate signature verification prior to version 1.4.1.
