Laranode versions before 1.2.1 contain a path traversal vulnerability in the POST /filemanager/upload-file endpoint that allows authenticated users to write arbitrary files outside their home directory. Attackers can supply directory traversal sequences in the path parameter to write PHP files into other tenants' web roots and execute code as those tenants.
