CVE-2019-10719
BlogEngine.NET 3.3.7.0 and earlier allows Directory Traversal and Remote Code Execution because file creation is mishandled, related to /api/upload and BlogEngine.NET/AppCode/Api/UploadController.cs.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (7.46%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
