Lifecycle Timeline
3Description
Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. An Uncontrolled Recursion vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft deep ASN.1 structures that trigger unbounded recursive parsing. This leads to a Denial-of-Service (DoS) via stack exhaustion when parsing untrusted DER inputs. This issue has been patched in version 1.3.2.
Analysis
Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Rated high severity (CVSS 8.7), this vulnerability is remotely exploitable, no authentication required, low attack complexity.
