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.
