Echo: werkzeug: security update to 3.1.9

medium Tenable Self-Hosted Container Security Plugin ID 473575

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 3.1.9, the safe_join function used by
send_from_directory can allow a NUL: special-device path because safe_join checks the Windows device name
without first removing an empty NTFS ADS marker. The trigger is that an application runs on Windows with
NTFS and serves a user-specified path ending in a special device name such as NUL:. The attack mechanism
is that a requested path ends in a Windows special device name with an empty ADS marker. The impact is
that the special device opens successfully and the file read hangs indefinitely. This issue is fixed in
version 3.1.9. (CVE-2026-102598)

Solution

Update the werkzeug library and its related packages to version 3.1.9 or later.
