CVE-2020-28502

An arbitrary code injection vulnerability was found in nodejs-xmlhttprequest. For this vulnerability to occur, the connection must be initialized during the function call XMLHttpRequest.open to send requests synchronously using the parameter async=False. If the subsequent calls to xhr.send functions are with user-controllable input, this flaw allows an attacker to execute arbitrary code. If the xhr.send function is called on the server on behalf of a user, this allows execution on the Node.js server using the privileges of the Node.js process. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
