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."}], "source": {"advisory": "GHSA-9wg5-mj3p-v49q", "discovery": "UNKNOWN"}}}}
