glpi-guard only reports already published advisories. If you discover a new vulnerability in GLPI, report it privately to the GLPI team: https://github.com/glpi-project/glpi/security/advisories/new (for a plugin, use the security advisory form of that plugin's repository). Please do not open a public issue here.
Use GitHub's private vulnerability reporting on this repository ("Security" tab → "Report a vulnerability").
glpi-guard is a defensive, read-only audit for installations you are responsible for. It contains no exploit code, performs no login attempts and has no feature to scan third-party systems. Contributions that add such features will not be accepted.
