## Description

elFinder is an open-source file manager for web, written in JavaScript using jQuery UI. Prior to 2.1.68, an authenticated SQL injection vulnerability in the elFinder MySQL volume driver (elFinderVolumeMySQL) allows any logged-in user, including users with read-only access to the affected volume, to inject SQL through a crafted target file hash. Successful exploitation can lead to unauthorized data disclosure and denial of service. This vulnerability only affects installations configured to use the MySQL volume driver. This vulnerability is fixed in 2.1.68.
