node-forge ASN.1 Unbounded Recursion
CVE: CVE-2025-66031
Component: node-forge
CWE: CWE-674
Severity: Moderate
CVSS v3: 5.3/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
Release date: 2025-11-26T22:23:26.013000+00:00

An ASN.1 Denial of Service (Dos) vulnerability exists in the node-forge asn1.fromDer function within forge/lib/asn1.js. The ASN.1 DER parser implementation (_fromDer) recurses for every constructed ASN.1 value (SEQUENCE, SET, etc.) and lacks a guard limiting recursion depth. An attacker can craft a small DER blob containing a very large nesting depth of constructed TLVs which causes the Node.js V8 engine to exhaust its call stack and throw RangeError: Maximum call stack size exceeded, crashing or incapacitating the process handling the parse. This is a remote, low-cost Denial-of-Service against applications that parse untrusted ASN.1 objects.

Red Hat OpenShift Pipelines is a cloud-native, continuous integration and
continuous delivery (CI/CD) solution based on Kubernetes resources.
It uses Tekton building blocks to automate deployments across multiple
platforms by abstracting away the underlying implementation details.
Tekton introduces a number of standard custom resource definitions (CRDs)
for defining CI/CD pipelines that are portable across Kubernetes distributions.
