Upgrade getgrav/grav to version 2.2.5 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 Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') via the dynamicFlexField method in FlexDirectory.php, where Flex form field directives embedded in page frontmatter are not restricted to safe operations. An authenticated attacker with edit access to a Flex object can supply arbitrary method names in page frontmatter directives, allowing them to invoke methods that modify or remove Flex objects, resulting in unauthorized data manipulation and potential partial data loss.
Note: This is only exploitable by a user who has been granted edit access to the targeted Flex object.
