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 0.6.0 and earlier is vulnerable to Regular Expression Denial of Service via a specially crafted string.
the web framework using ljharb's qs module older than v6.3.2, v6.2.3, v6.1.2, and v6.0.4 is vulnerable to a DoS. A malicious user can send a evil request to cause the web framework crash.
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.
