Description Andrej Nemec 2016-06-17 07:44:51 EDT

negotiator is an HTTP content negotiator for Node.js and is used by many modules and frameworks including Express and Koa.

The header for "Accept-Language", when parsed by negotiator is vulnerable to Regular Expression Denial of Service via a specially crafted string.
