CVE-2026-39844

NiceGUI

Popis

NiceGUI is a Python-based UI framework. Prior to 3.10.0, Since PurePosixPath only recognizes forward slashes (/) as path separators, an attacker can bypass this sanitization on Windows by using backslashes (\) in the upload filename. Applications that construct file paths using file.name (a pattern demonstrated in NiceGUI-s bundled examples) are vulnerable to arbitrary file write on Windows. This vulnerability is fixed in 3.10.0.
