SCA: security update for werkzeug (GHSA-hgf8-39gv-g3f2)
medium Tenable Cloud Security Plugin ID 437060
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Werkzeug is a comprehensive WSGI web application library. Prior to version 3.1.4, Werkzeug's safe_join
function allows path segments with Windows device names. On Windows, there are special device names such
as CON, AUX, etc that are implicitly present and readable in every directory. send_from_directory 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 patched in version 3.1.4. (CVE-2025-66221)
