Last modified
CVE-2013-6401 is a vulnerability of currently unknown severity. Jansson, possibly 2.4 and earlier, does not restrict the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted JSON document.. EPSS estimates a 1.95% chance of exploitation in the next 30 days.
