Description

Pi.Alert is a WIFI / LAN intruder detector with web service monitoring. Prior to 2026-05-07, Pi.Alert&#39;s SaveConfigFile() endpoint writes user-supplied numeric config values (e.g., SMTP_PORT) directly into<br /> pialert.conf without validation. Since pialert.conf is loaded via Python&#39;s exec() every 3–5 minutes by the<br /> background cron process, an attacker can inject arbitrary Python code and achieve unauthenticated OS-level RCE. On<br /> default installations (PIALERT_WEB_PROTECTION = False), no credentials are required. This vulnerability is fixed in 2026-05-07.
