CVE-2011-4461
Jetty 8.1.0.RC2 and earlier computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.
Does this matter?
Lower severity and a low EPSS score (4.92%). Track it; it rarely justifies an emergency change on its own.
