{"id":"CVE-2026-118774","state":"PUBLISHED","title":"Forge: Certificate signature verified with the issuer's RSA signature scheme","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.","publishedAt":"2026-10-29T18:33:46.399Z","updatedAt":"2026-10-29T18:33:46.399Z","severity":{"score":3.7,"label":"Low","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["digitalbazaar forge"],"affected":[{"vendor":"digitalbazaar","product":"forge","versions":[{"version":"< 1.4.1","status":"affected"}]}],"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"],"weaknesses":["CWE-347"],"ingestedAt":"2026-10-29T20:10:52.580Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/118xxx/CVE-2026-118774.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-118774","state":"PUBLISHED","datePublished":"2026-10-29T18:33:46.399Z","dateUpdated":"2026-10-29T18:33:46.399Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-10-28T19:20:05.018Z"},"containers":{"cna":{"title":"Forge: Certificate signature verified with the issuer's RSA signature scheme","descriptions":[{"lang":"en","value":"Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript.
