Upgrade getgrav/grav to version 2.2.13 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 Exposed Dangerous Method or Function via the extend() method in Blueprint.php, where untrusted Flex form override fields can exploit merge operations that rename or renumber field keys. When deepMerge() processes replace-name@ or unset-name@ directives, it relocates a field - along with any embedded data-*@ directives - to a top-level key that dynamicPathsOf() never enumerates, causing init() to fall back to the blueprint's own file trust for that key and bypass the allowlist. An authenticated attacker can supply a manipulated form override to escalate privileges or achieve remote code execution.
