CVE-2016-9014
Django before 1.8.x before 1.8.16, 1.9.x before 1.9.11, and 1.10.x before 1.10.3, when settings.DEBUG is True, allow remote attackers to conduct DNS rebinding attacks by leveraging failure to validate the HTTP Host header against settings.ALLOWED_HOSTS.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.07%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
