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.

A flaw was found in Axios. A remote attacker or an unresponsive endpoint can cause a Denial of Service (DoS) by triggering an error during HTTP/2 session initialization or reuse. Because the underlying session fails to register proper error handlers, network or session failures result in an uncaught exception that abruptly terminates the application process.

This vulnerability is rated as having an Important severity because an unhandled runtime error can terminate the entire host Node.js application process, leading to complete service unavailability. In Red Hat environments, the exposure is limited to server-side Node.js workloads specifically configured to initiate outgoing HTTP/2 connections, whereas standard deployments relying on the default HTTP/1.1 transport or running within client browsers remain unaffected. Exploitation requires an application to connect to an external server that induces connection or session errors, allowing a remote endpoint to crash the relying service.
