CVE-2016-2515
Hawk before 3.1.3 and 4.x before 4.1.1 allow remote attackers to cause a denial of service (CPU consumption or partial outage) via a long (1) header or (2) URI that is matched against an improper regular expression.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.37%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
