Werkzeug

Werkzeug versions 3.1.5 and below on Windows fail to properly filter reserved device names in the safe_join function when paths contain multiple segments, allowing attackers to craft requests that trigger indefinite hangs by targeting special device names like NUL. Remote attackers can exploit this denial-of-service vulnerability against applications using send_from_directory to serve user-specified files. A patch is available in version 3.1.6.

Werkzeug versions prior to 3.1.5 fail to properly validate Windows reserved device names in the safe_join function, allowing attackers to bypass path restrictions by using device names with file extensions or trailing spaces (e.g., CON.txt, AUX ). This denial of service vulnerability affects Windows systems running vulnerable Werkzeug versions and could allow an unauthenticated remote attacker to access restricted files or cause application crashes. A patch is available in version 3.1.5 and later.
