SCA: security update for Glances (GHSA-vx5f-957p-qpvm)

high Tenable Cloud Security Plugin ID 438843

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. Prior to version 4.5.2, in Central
 Browser mode, Glances stores both the Zeroconf-advertised server name and the discovered IP address for
 dynamic servers, but later builds connection URIs from the untrusted advertised name instead of the
 discovered IP. When a dynamic server reports itself as protected, Glances also uses that same untrusted
 name as the lookup key for saved passwords and the global `[passwords] default` credential. An attacker on
 the same local network can advertise a fake Glances service over Zeroconf and cause the browser to
 automatically send a reusable Glances authentication secret to an attacker-controlled host. This affects
 the background polling path and the REST/WebUI click-through path in Central Browser mode. Version 4.5.2
 fixes the issue. (CVE-2026-32634)

Solution

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