Axios is a promise based HTTP client for the browser and Node.js. Starting in version 1.13.0 and prior to 1.13.2, Axios HTTP/2 session cleanup logic contains a state corruption bug that allows a malicious server to crash the client process through concurrent session closures. The vulnerability exists in the Http2Sessions.getSession() method in lib/adapters/http.js. The session cleanup logic contains a control flow error when removing sessions from the sessions array. This vulnerability is fixed in 1.13.2.
