CVE-2026-52817Public exploit

Root privilege escalation via apt-get arguments

Published Aug 18, 2026 · Updated Aug 19, 2026

Argument injection in Debian.sudoers in Linuxfabrik Monitoring Plugins before 5.1.0 allows local users to gain root via apt-get options. The assets/sudoers/Debian.sudoers rule permits /usr/bin/apt-get as root without pinning the required argument list, so the nagios or icinga account can pass APT::Update::Pre-Invoke to run an arbitrary command when apt-get starts. Exposure is limited to hosts that installed the shipped Debian-family sudoers drop-in and where attackers already control the monitoring account, but successful exploitation yields a root shell and full host compromise.
