## Overview

Axios is a promise-based HTTP client for the browser and Node.js. From 1.13.0 until 1.20.0, Http2Sessions does not install adequate error handling for a ClientHttp2Session during Axios HTTP/2 session initialization or reuse. A request uses httpVersion: 2 and the ClientHttp2Session emits an error during session initialization or reuse. The unhandled session error escapes normal Promise rejection handling. The uncaught error can terminate the Node.js process and cause denial of service. This issue is fixed in version 1.20.0.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
