Improper Verification Of Cryptographic Signature

node-forge is vulnerable to Improper Verification of Cryptographic Signature. The vulnerability is due to insufficient validation of RSASSA PKCS1 v1.5 signatures allowing malformed ASN structures and inadequate padding checks, which allows an attacker to forge valid signatures and bypass signatur...
