CVE-2026-73974

linuxfabrik-lib provides Python modules for database access, caching, shell execution, and API integrations, and Linuxfabrik Monitoring Plugins uses its shared testing helper across check plugins. Prior to linuxfabrik-lib 6.1.0 and Linuxfabrik Monitoring Plugins 7.0.0, lib.lftest.test treated the...

GHSA-RH9C-RQVG-F7PR linuxfabrik-lib: Arbitrary root file read via live --test argument (lib.lftest) across sudoers-whitelisted plugins (LPE)

Summary Every Linuxfabrik check plugin that supports the shared --test argument routed through lib.lftest.test will, when --test is supplied, treat the first CSV element as a filesystem path and read its full contents as the plugin's simulated STDOUT — running as root when the plugin is invoked...

CVE-2026-55426

linuxfabrik-lib provides Python modules for database access, caching, shell execution, and API integrations, and Linuxfabrik Monitoring Plugins uses those modules to run external monitoring commands. From the earliest affected releases until linuxfabrik-lib 5.0.0 and Linuxfabrik Monitoring Plugin...

CVE-2026-53759

linuxfabrik-lib provides Python modules for database access, caching, shell execution, and API integrations. Prior to version 4.2.0, dbsqlite.py created SQLite databases at predictable paths in the shared /tmp directory and followed attacker-created symbolic links at those paths. An attacker who...

CVE-2026-73974

linuxfabrik-lib (prior to 6.1.0) and Linuxfabrik Monitoring Plugins (prior to 7.0.0) contain an arbitrary root file-read vulnerability in the lib.lftest.test() helper. The hidden --test argument (mapped to argparse.SUPPRESS, invisible in --help but accepted at runtime) treats its first or second ...

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...

CVE-2026-55426 linuxfabrik-lib: Local privilege escalation using embedded command

CVE-2026-53759 linuxfabrik-lib: Insecure creation of SQLite databases

linuxfabrik-lib provides Python modules for database access, caching, shell execution, and API integrations. Prior to version 4.2.0, dbsqlite.py created SQLite databases at predictable paths in the shared /tmp directory and followed attacker-created symbolic links at those paths. An attacker who...

CVE-2026-53759

In linuxfabrik-lib versions before 4.2.0, db_sqlite.py created SQLite databases at predictable /tmp paths and followed attacker-created symlinks. A compromised local account (e.g., nagios) could create a symlink and trigger a sudo-authorized plugin, causing a root process to write to arbitrary pa...
