Versions of @hapi/hapi prior to 18.4.1 or 19.1.1 are vulnerable to Denial of Service. The CORS request handler has a vulnerability which will cause the function to throw a system error if the header contains some invalid values. If no unhandled exception handler is available, the application will exist, allowing an attacker to shut down services.

Upgrade to versions 18.4.1, 19.1.1 or later.
