Description Pedro Sampaio 2018-06-07 20:40:11 UTC 
Fresh is a module used by the Express.js framework for HTTP response freshness testing. It is vulnerable to a regular expression denial of service when it is passed specially crafted input to parse. This causes the event loop to be blocked causing a denial of service condition.
