Overview
Affected versions of this package are vulnerable to Incomplete List of Disallowed Inputs via the defaultSanitizer function in FileAdder.php. An attacker can upload files with double extensions or omitted executable extensions, potentially leading to remote code execution by bypassing file type restrictions. This can be achieved by uploading files such as shell.php.jpg or files with extensions like .php6, .shtml, or .htaccess. This is only exploitable if a legacy Apache AddHandler configuration is present, which allows execution of files with certain extensions.
