CWE-22  (opens in a new tab)

How to fix?

Upgrade getgrav/grav to version 1.7.45 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 Path Traversal due to improper handling of file upload paths. An attacker can replace or create files with specific extensions such as .json, .zip, .css, .gif, etc., by exploiting the path traversal flaw. This could lead to arbitrary code execution on the server, compromise the integrity of backup files by overwriting existing ones or creating new ones, and enable the exfiltration of sensitive data through CSS exfiltration techniques.
