CVE-2026-62982

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.

Summary		(es) Glances es una herramienta de monitoreo de sistema multiplataforma de código abierto. Desde la versión 4.5.2 hasta la 4.5.6, _sanitize_mustache_dict() en glances/actions.py omite cadenas de listas y diccionarios anidados, como los valores de cmdline de proceso, permitiendo que los caracteres de barra vertical sobrevivan a chevron.render() y sean ejecutados por secure_popen() a través de plantillas de acción configuradas por el administrador. Este problema está corregido en la versión 4.5.6.
