Description

A flaw was found in Axios, a promise-based HTTP client. A malicious server can exploit a state corruption bug within the HTTP/2 session cleanup logic, specifically in the Http2Sessions.getSession() method. By initiating concurrent session closures, the server can trigger a control flow error, leading to a client process crash. This vulnerability results in a Denial of Service (DoS) for the client application.
