CVE-2026-119187: forge — Exploit & Fix

Description

Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Prior to 1.4.1, the affected implementation used forge.tls.createConnection(), TLS record processing, process() to process the relevant input or security decision. node-forge processed received TLS records recursively, consuming one JavaScript stack frame per record in a single input chunk. A remote peer could send thousands of small records together and exhaust the call stack, causing an uncaught exception and denial of service. This issue is fixed in version 1.4.1.
