Werkzeug safe_join() allows Windows special device names

Werkzeug's safejoin function allows Windows device names as filenames when they have an empty ADS marker on NTFS. This was previously reported as https://github.com/pallets/werkzeug/security/advisories/GHSA-hgf8-39gv-g3f2, but the added filtering failed to account for the fact Windows allows...

BIT-PHP-MIN-2026-17545 PHP on Windows: Reserved Device Names Are Not Rejected Before File/Stream I/O which can cause DoS

On Windows, PHP's filesystem and stream APIs do not reject reserved device names such as CON, PRN, AUX, NUL, COM1 to COM9, LPT1 to LPT9, CONIN$ and CONOUT$ when they appear as a component of a path. An attacker-controlled filename therefore reaches CreateFileW and opens a device instead of the...

curl: Windows filename sanitizer misses Unicode COM/LPT reserved device names

Hi all, I found a way for a server-selected Windows filename to bypass curl's reserved DOS device-name sanitizer. With curl -O -J, a Content-Disposition filename such as COM¹, COM², COM³, LPT¹, LPT², or LPT³ is left unchanged, even though Windows treats all six as reserved device names. Curl...
