What is CVE-2018-3814?

Craft CMS version 2.6.3000 contains a vulnerability that permits remote attackers to execute arbitrary PHP code. This is achieved through the 'Assets->Upload files' feature, where a malicious user can upload a .jpg file that contains embedded PHP code. By using the 'Replace it' option, they can rename this file to a .php extension, enabling the execution of the embedded code on the server. This vulnerability underscores the necessity of stringent file validation and secure handling of user-uploaded content to mitigate potential risks.
