CVE-2026-55426

The shell_exec() function in linuxfabrik-lib splits command strings on pipe characters, enabling command injection via attacker-controlled arguments (e.g., --repo '|touch /root/nagios-was-here|') in plugins like restic-check. If a plugin is in the sudoers file, a compromised nagios/icinga account...
