Description Andrej Nemec 2017-10-11 07:16:33 EDT

method-override is a module used by the Express.js framework to let you use HTTP verbs such as PUT or DELETE in places where the client doesn't support it.

method-override is vulnerable to a regular expression denial of service vulnerability when specially crafted input is passed in to be parsed via the X-HTTP-Method-Override header.
