What is GHSA-mg85-8mv5-ffjr?
GHSA-mg85-8mv5-ffjr is a denial of service vulnerability in ammo, published on 3 Sep 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
All versions of ammo are vulnerable to Denial of Service. The Range HTTP header parser has a vulnerability which will cause the function to throw a system error if the header is set to an invalid value. Because hapi is not expecting the function to ever throw, the error is thrown all the way up the stack. If no unhandled exception handler is available, the application will exist, allowing an attacker to shut down services.
Recommendation
This package is deprecated and is now maintained as @hapi/ammo. Please update your dependencies to use @hapi/ammo.
