CVE-2026-27199
Werkzeug's
safe_joinfunction allows Windows device names as filenames if when 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
safe_joinaccepts paths with multiple segments, such asexample/NUL.send_from_directoryusessafe_jointo 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.Release Notes
