Linux Distros Unpatched Vulnerability : CVE-2026-55798

medium Nessus Plugin ID 325512

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
