Hawk used a regular expression to parse Host HTTP header (Hawk.utils.parseHost()), which was subject to regular expression DoS attack - meaning each added character in the attacker s input increases the computation time exponentially. parseHost() was patched in 9.0.1 to use built-in URL class to parse hostname instead. Hawk.authenticate() accepts options argument. If that contains host and port, those would be used instead of a call to utils.parseHost().(CVE-2022-29167)",
