CVE-2017-14949
Restlet Framework before 2.3.12 allows remote attackers to access arbitrary files via a crafted REST API HTTP request that conducts an XXE attack, because only general external entities (not parameter external entities) are properly considered.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.41%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
