CVE-2026-119191— Forge: ASN.1 resource exhaustion via BIT STRING decoding in asn1.fromDer

Quick assessment

Affected
digitalbazaar forge
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 JavaScript 中传输层安全协议（TLS）的原生实现。在 1.4.1 版本之前，受影响的实现在处理相关输入或做出安全决策时，使用了 asn1.fromDer() 函数、BIT STRING 解码以及 maxDepth 参数。node-forge 在解码存储在 BIT STRING 值中的 ASN.1 数据时，未能始终一致地应用配置的 maxDepth 限制，并在每一层嵌套中递归地保留副本。精心构造的包含嵌套 BIT STRING 的 DER 数据，可能在调用 as

Vulnerability Title
Forge: ASN.1 resource exhaustion via BIT STRING decoding in asn1.fromDer
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 asn1.fromDer(), BIT STRING decoding, maxDepth to process the relevant input or security decision. node-forge decoded ASN.1 stored inside BIT STRING values without consistently applying the configured maxDepth limit and recursively retained copies at each nesting level. Crafted DER containing nested BIT STRINGs could cause excessive recursion, CPU use, and quadratic memory consumption during asn1.fromDer(). This issue is fixed in version 1.4.1.
