{"affected":[{"product":"forge","source":"CNA: GitHub_M","vendor":"digitalbazaar","versions":[{"status":"affected","version":"< 1.4.1"}]}],"cveId":"CVE-2026-118774","cwes":["CWE-347"],"description":"Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. 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.","epss":{"date":"2026-11-03","percentile":0.0112,"score":0.00107},"exploits":[],"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:L/A:N","version":"3.1"},{"score":3.7,"severity":"low","source":"NVD: security-advisories@github.com","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"}],"modifiedAt":1793726279973,"publishedAt":1793298826399,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-9wg5-mj3p-v49q"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/digitalbazaar/forge/commit/c7f42614d5166a77ddf11ce174b2601b14f6956b"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/digitalbazaar/forge/releases/tag/v1.4.1"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/digitalbazaar/forge/commit/c7f42614d5166a77ddf11ce174b2601b14f6956b"},{"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-9wg5-mj3p-v49q"}],"remediation":[],"revision":"acb7892b72097c5976564288765156ff34d5278edb5ae7b79095bfc8664f15d0","sources":[{"modifiedAt":1793722641117,"name":"CNA: GitHub_M","retrievedAt":1793725824639,"url":"https://www.cve.org/CVERecord?id=CVE-2026-118774"},{"modifiedAt":1793726279973,"name":"NVD","retrievedAt":1793729932620,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-118774"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793725830100,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-118774"}],"ssvc":{"assessedAt":1793722062750,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Forge: Certificate signature verified with the issuer's RSA signature scheme","updatedAt":1793729932620}
