CVE-2026-41229
Published:April 23, 2026
Updated:May 18, 2026
Froxlor is open source server administration software. Prior to version 2.3.6, "PhpHelper::parseArrayToString()" writes string values into single-quoted PHP string literals without escaping single quotes. When an admin with "change_serversettings" permission adds or updates a MySQL server via the API, the "privileged_user" parameter (which has no input validation) is written unescaped into "lib/userdata.inc.php". Since this file is "require"d on every request via "Database::getDB()", an attacker can inject arbitrary PHP code that executes as the web server user on every subsequent page load. Version 2.3.6 contains a patch.
