Doc Text:
A flaw was found in Glances, an open-source system monitoring tool. An attacker who can modify or influence Glances' configuration files can inject malicious system commands. These commands are automatically executed with the privileges of the Glances process during startup or configuration reload. This command injection vulnerability allows for arbitrary code execution and could lead to privilege escalation if Glances is running with elevated privileges.

Description OSIDB Bzimport 2026-04-02 16:03:31 UTC 
Glances is an open-source system cross-platform monitoring tool. Prior to version 4.5.3, Glances supports dynamic configuration values in which substrings enclosed in backticks are executed as system commands during configuration parsing. This behavior occurs in Config.get_value() and is implemented without validation or restriction of the executed commands. If an attacker can modify or influence configuration files, arbitrary commands will execute automatically with the privileges of the Glances process during startup or configuration reload. In deployments where Glances runs with elevated privileges (e.g., as a system service), this may lead to privilege escalation. This issue has been patched in version 4.5.3.
