CVE-2026-119187— Forge: Denial of service in TLS record processing via call stack exhaustion

Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Forge（也称为 node-forge）是一个用 JavaScript 实现的原生传输层安全（TLS）库。在 1.4.1 版本之前，受影响的实现通过 方法创建连接，并调用 TLS 记录处理函数 来处理相关输入或做出安全决策。node-forge 对接收到的 TLS 记录采用递归方式处理，单个输入块中的每条记录都会消耗一个 JavaScript 调用栈帧。远程对等方可以一次性发送数千条小记录，从而耗尽调用栈，引发未捕获的异常并导致拒绝服务（DoS）。该问题已在 1.4.1 版本中修复。

Vulnerability Title
Forge: Denial of service in TLS record processing via call stack exhaustion
Source: CVE Program / CVE List V5
Vulnerability 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.
