Official description

Pi.Alert is a WIFI / LAN intruder detector with web service monitoring. From 2024-06-29 to before 2026-05-07, the web application endpoint is vulnerable to SQL injection. The /pialert/php/server/devices.php route accepts requests from unauthenticated users when the action URL parameter is set to getDevicesTotals. The scansource URL parameter is then injected in a SQL query. This vulnerability is fixed in 2026-05-07.
