Node axios: From 1.13.0 until 1.20.0, Http2Sessions does not install adequate error handling for a ClientHttp2Session during Axios HTTP/2 session initialization… (CVE-2026-101901)
Description
Axios versions from 1.13.0 up to but not including 1.20.0 have a vulnerability in HTTP/2 session initialization where inadequate error handling for ClientHttp2Session errors can cause unhandled exceptions. This can lead to the termination of the Node.js process and result in denial of service. The issue is fixed in version 1.20.0.

Technical Analysis
Axios, a promise-based HTTP client for Node.js and browsers, versions 1.13.0 through 1.19.x do not properly handle errors emitted by ClientHttp2Session during HTTP/2 session initialization or reuse. When a request uses HTTP/2 and the ClientHttp2Session emits an error, the error is not caught by normal Promise rejection handlers, causing an unhandled exception that can crash the Node.js process and cause denial of service. This vulnerability is resolved in Axios version 1.20.0.
Potential Impact
An attacker can cause the Node.js process using Axios HTTP/2 client to terminate unexpectedly by triggering an error during HTTP/2 session initialization or reuse. This results in a denial of service condition. There is no indication of remote code execution or data compromise from the provided data.
Mitigation Recommendations
Upgrade Axios to version 1.20.0 or later where this issue is fixed. No other mitigation is indicated or required according to the available information.
