CVE-2025-66030 – node-forge ASN.1 OID Integer Truncation

CVE ID : CVE-2025-66030

Published : Nov. 26, 2025, 11:15 p.m. | 1 hour, 6 minutes ago

Description : Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. An Integer Overflow 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. This issue has been patched in version 1.3.2.

Severity: 6.3 | MEDIUM
