How to fix?

Upgrade getgrav/grav to version 1.74.2 or higher.

Overview

getgrav/grav is a Modern, Crazy Fast, Ridiculously Easy and Amazingly Powerful Flat-File CMS.

Affected versions of this package are vulnerable to Remote Code Execution (RCE) via the default filter() function, which did not block other built-in functions exposed by Twig's Core Extension that could be used to invoke arbitrary unsafe functions, and allowing the exploitation of this vulnerability.

This vulnerability derives due to an improper fix of CVE-2022-2073.
