SCA: security update for Glances (GHSA-hhcg-r27j-fhv9)

medium Tenable Cloud Security Plugin ID 438836

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. Glances recently added DNS rebinding
 protection for the MCP endpoint, but prior to version 4.5.2, the main REST/WebUI FastAPI application still
 accepts arbitrary `Host` headers and does not apply `TrustedHostMiddleware` or an equivalent host
 allowlist. As a result, the REST API, WebUI, and token endpoint remain reachable through attacker-
 controlled domains in classic DNS rebinding scenarios. Once the victim browser has rebound the attacker
 domain to the Glances service, same-origin policy no longer protects the API because the browser considers
 the rebinding domain to be the origin. This is a distinct issue from the previously reported default CORS
 weakness. CORS is not required for exploitation here because DNS rebinding causes the victim browser to
 treat the malicious domain as same-origin with the rebinding target. Version 4.5.2 contains a patch for
 the issue. (CVE-2026-32632)

Solution

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