The Axios HTTP client, used widely in both browser and Node.js environments, is susceptible to a state corruption bug related to HTTP/2 session cleanup. This flaw, present in versions prior to 1.13.2, allows malicious servers to exploit the session handling logic, potentially causing the client process to crash during simultaneous session closures. This issue is rooted in the control flow error within the Http2Sessions.getSession() method. Users are advised to upgrade to version 1.13.2 or later to mitigate this risk.
