Overview
org.webjars.npm:node-forge is a WebJar for node-forge.
Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the derToOid function in the asn1.js file, which decodes ASN.1 structures containing OIDs with oversized arcs. An attacker can bypass security decisions based on OID validation by crafting malicious ASN.1 data that exploits 32-bit bitwise truncation.
