Echo: pillow: security update to 12.3.0

medium Tenable Self-Hosted Container Security Plugin ID 460919

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Pillow is a Python imaging library. Prior to 12.3.0, WindowsViewer.get_command() constructed a cmd.exe
 shell command by directly embedding a file path into an f-string without escaping and passed the result to
 subprocess.Popen(..., shell=True), allowing shell metacharacters in the file path to inject arbitrary
 cmd.exe commands. This issue is fixed in version 12.3.0. (CVE-2026-55798)

Solution

Update the pillow library and its related packages to version 12.3.0 or later.
