SCA: security update for Glances (GHSA-7p93-6934-f4q7)

high Tenable Self-Hosted Container Security Plugin ID 440912

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 4.5.3, the Glances XML-
 RPC server (activated with glances -s or glances --server) sends Access-Control-Allow-Origin: * on every
 HTTP response. Because the XML-RPC handler does not validate the Content-Type header, an attacker-
 controlled webpage can issue a CORS "simple request" (POST with Content-Type: text/plain) containing a
 valid XML-RPC payload. The browser sends the request without a preflight check, the server processes the
 XML body and returns the full system monitoring dataset, and the wildcard CORS header lets the attacker's
 JavaScript read the response. The result is complete exfiltration of hostname, OS version, IP addresses,
 CPU/memory/disk/network stats, and the full process list including command lines (which often contain
 tokens, passwords, or internal paths). This issue has been patched in version 4.5.3. (CVE-2026-33533)

Solution

Update the Glances library and its related packages to version 4.5.3 or later.
