CVE-2026-68518: Nicolargo Glances

High severity, CVSS 8.8. EPSS: 0.2% chance of exploitation in the next 30 days.

Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.6, _sanitize_mustache_dict() in glances/actions.py sanitizes individual Mustache values before chevron.render(), allowing adjacent unescaped Mustache variables to reconstruct shell operators that secure_popen() executes when attacker-controlled process or container fields are rendered by an administrator-configured action template. This issue is fixed in 4.5.6.

Affected products

• Nicolargo Glances: before 4.5.6 (fixed in 4.5.6)
