NVD description

Glances is an open-source system cross-platform monitoring tool. From 4.5.2 until 4.5.6, _sanitize_mustache_dict() in glances/actions.py skips nested list and dictionary strings such as process cmdline values, allowing pipe characters to survive chevron.render() and be executed by secure_popen() through administrator-configured action templates. This issue is fixed in 4.5.6.

Disclosure
A flaw in glances bypassed shell operator checks because its sanitizer only inspected top-level strings. Attacker-controlled lists (like cmdline) passed through raw into templates, enabling OS command injection (CVE-2026-62982). https://github.com/advisories/GHSA-73wf-9vmv-5pv9 https://t.co/zG7JFvIImm
Post summary
This tweet discloses a new OS command injection flaw in glances, detailing how sanitizer limitations allow raw input to be executed, and provides a GitHub advisory link for further information.
