CVE-2018-3814: Craft CMS

High severity, CVSS 8.8. EPSS: 1.9% chance of exploitation in the next 30 days.

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.
