Is this vulnerability remotely exploitable?

Exploitation depends on how configuration files are managed. If configuration is only locally editable by administrators, the risk is primarily local. However, if configuration is sourced from remote services, templates, or APIs that attackers can influence, an effective remote vector may exist.

What level of access does an attacker need to exploit this?

The attacker needs the ability to create, modify, or influence Glances configuration files or any upstream configuration inputs processed by `Config.get_value()`. This might include local filesystem write access, control over configuration templates, or access to configuration management pipelines.

What is the safest general fix pattern?

The safest pattern is to remove or disable command execution in the configuration layer entirely. Configuration values should be treated as plain data, with no automatic evaluation of backtick-enclosed or other special syntaxes as system commands, and any required dynamic behavior should use safe, non-shell mechanisms.
