Defenders should note that Glances reads command lines from the glances.conf file. If an attacker gains write access to this configuration file, they can inject shell operators such as && (chaining), | (pipe), or > (file redirection) into alert action fields. Because the glances/actions.py module fails to pass the allow_operators constraint to the secure_popen() function in the alert action code path, these injected commands are executed with the privileges of the Glances process. This vulnerability effectively negates the security guarantees provided by the --disable-config-exec flag.

Impact

Successful exploitation allows an attacker with access to modify the Glances configuration file to achieve arbitrary command execution or unauthorized file writes. This represents a significant escalation of privilege or persistence mechanism, as the commands execute under the security context of the Glances daemon or user process.

Recommendation

• Upgrade Glances to the version addressing CVE-2026-68519 as soon as it becomes available.
• Audit the integrity of the glances.conf file across all monitored environments to ensure no unauthorized alert actions have been injected.
• Restrict write access to the glances.conf file to a minimal set of highly privileged administrative users.
• Monitor for unexpected process creation events spawned by the glances process, specifically processes launched as children of the main Glances application.
