{"id":"CVE-2026-118774","published":"2026-10-29T19:17:19.863","lastModified":"2026-10-29T19:17:19.863","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.","cvssScore":3.7,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N","cwes":["CWE-347"],"vendors":[],"products":[],"references":[{"url":"https://github.com/digitalbazaar/forge/commit/c7f42614d5166a77ddf11ce174b2601b14f6956b","tags":[]},{"url":"https://github.com/digitalbazaar/forge/releases/tag/v1.4.1","tags":[]},{"url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-9wg5-mj3p-v49q","tags":[]}],"exploitRefs":[{"url":"https://github.com/digitalbazaar/forge/commit/c7f42614d5166a77ddf11ce174b2601b14f6956b","tags":[]},{"url":"https://github.com/digitalbazaar/forge/releases/tag/v1.4.1","tags":[]},{"url":"https://github.com/digitalbazaar/forge/security/advisories/GHSA-9wg5-mj3p-v49q","tags":[]}],"hasPoc":true,"ai":null}
