What is GHSA-5854-jvxx-2cg9?
GHSA-5854-jvxx-2cg9 is a denial of service vulnerability in content, published on 3 Sep 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Versions of content are vulnerable to Denial of Service. The Content-Encoding HTTP header parser has a vulnerability which will cause the function to throw a system error if the header contains some invalid values. Because hapi rethrows system errors (as opposed to catching expected application errors), 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/content. Please update your dependencies to use @hapi/content.
