7.5 highCVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HCVE-2017-16118
High (7.5) in forwarded project forwarded. EPSS 1.9% chance of exploitation in the next 30 days. Fixed in forwarded 0.1.2.
The forwarded module is used by the Express.js framework to handle the X-Forwarded-For header. It is vulnerable to a regular expression denial of service when it's passed specially crafted input to parse. This causes the event loop to be blocked causing a denial of service condition.
