Upgrade getgrav/grav to version 2.0.25 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 Improper Handling of Case Sensitivity via the web.config or lighttpd.conf configuration files due to case-sensitive access-control deny rules. An attacker can access sensitive files and disclose confidential information by varying the case of folder names or file extensions in HTTP requests. This is only exploitable if the application is deployed on IIS with case-insensitive NTFS or on lighttpd with a case-insensitive filesystem and the relevant configuration files are used without additional protections.
