CVE-2026-68517: Glances is an open-source system cross-platform monitoring tool

Routine

MEDIUM 6.5

CVE-2026-68517 is a medium-severity flaw (CVSS 6.5) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.6, the cors_origins guard in glances/outputs/glances_restful_api.py uses exact list equality instead of wildcard membership, allowing a multi-origin list containing the wildcard to retain cors_credentials and expose authenticated REST API data to an untrusted website visited by a previously authenticated user. This issue is fixed in 4.5.6.

Why this priority

CISA SSVC: public proof of concept

A fixed release or distro patch exists.
