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

      "value": "Pi.Alert es un detector de intrusos WIFI / LAN con monitoreo de servicios web. Antes del 07-05-2026, el endpoint SaveConfigFile() de Pi.Alert escribe valores de configuración numéricos proporcionados por el usuario (por ejemplo, SMTP_PORT) directamente en pialert.conf sin validación. Dado que pialert.conf se carga a través de exec() de Python cada 3-5 minutos por el proceso cron en segundo plano, un atacante puede inyectar código Python arbitrario y lograr RCE a nivel de sistema operativo no autenticado. En instalaciones predeterminadas (PIALERT_WEB_PROTECTION = False), no se requieren credenciales. Esta vulnerabilidad se corrigió el 07-05-2026."
