CVE-2018-3814
Craft CMS 2.6.3000 allows remote attackers to execute arbitrary PHP code by using the "Assets->Upload files" screen and then the "Replace it" option, because this allows a .jpg file to have embedded PHP code, and then be renamed to a .php extension.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.88%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
