Werkzeug is a comprehensive WSGI web application library. Versions 3.1.5 and below, the safejoin function allows Windows device names as filenames if preceded by other path segments. This was previously reported as GHSA-hgf8-39gv-g3f2, but the added filtering failed to account for the fact that safejoin accepts paths with multiple segments, such as example/NUL. The function sendfromdirectory uses safe_join to safely serve files at user-specified paths under a directory. If the application is running on Windows, and the requested path ends with a special device name, the file will be opened successfully, but reading will hang indefinitely. This issue has been fixed in version 3.1.6.
