Background
The soketi package is an npm package that provides a server implementation for the Pusher Protocol. It allows users to create real-time applications using WebSockets. The package is widely used by developers to build applications that require real-time communication. However, a vulnerability has been discovered in versions prior to 0.24.1 that can lead to a denial of service (DoS) attack.
Vulnerability Detail
The vulnerability in soketi arises from a wrong behavior when reading POST requests. If a POST request with an empty body is sent to any endpoint of the server, including unauthenticated requests, the server crashes when trying to send a response after the request is closed. This vulnerability affects all users of the server. An attacker can exploit this vulnerability by sending multiple empty POST requests, causing the server to crash and become unresponsive. The impact of this vulnerability is a DoS attack, which can disrupt the availability of the server and the applications relying on it.
