Overview
getgrav/grav is a Modern, Crazy Fast, Ridiculously Easy and Amazingly Powerful Flat-File CMS.
Affected versions of this package are vulnerable to Arbitrary Code Injection in the sort filter due to improper handling of the isSandboxed argument in the sortFunc wrapper. An attacker can execute arbitrary PHP code by supplying a crafted payload that invokes spl_autoload through the sort filter, leading to code execution as the web server user. This is only exploitable if the attacker has authenticated access with page-write rights (such as admin.pages or api.pages.write).
