CVE-2025-66030: node-forge is vulnerable to ASN.1 OID Integer Truncation

November 26, 2025 (updated December 1, 2025)

MITRE-Formatted CVE Description An Integer Overflow (CWE-190) vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft ASN.1 structures containing OIDs with oversized arcs. These arcs may be decoded as smaller, trusted OIDs due to 32-bit bitwise truncation, enabling the bypass of downstream OID-based security decisions.
