SCA: security update for Glances (GHSA-vcv2-q258-wrg7)

high Tenable Cloud Security Plugin ID 438846

Description

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

 - Glances is an open-source system cross-platform monitoring tool. The Glances action system allows
 administrators to configure shell commands that execute when monitoring thresholds are exceeded. These
 commands support Mustache template variables (e.g., `{{name}}`, `{{key}}`) that are populated with runtime
 monitoring data. The `secure_popen()` function, which executes these commands, implements its own pipe,
 redirect, and chain operator handling by splitting the command string before passing each segment to
 `subprocess.Popen(shell=False)`. Prior to 4.5.2, when a Mustache-rendered value (such as a process name,
 filesystem mount point, or container name) contains pipe, redirect, or chain metacharacters, the rendered
 command is split in unintended ways, allowing an attacker who controls a process name or container name to
 inject arbitrary commands. Version 4.5.2 fixes the issue. (CVE-2026-32608)

Solution

Update the Glances library and its related packages to version 4.5.2 or later.
