Unauthenticated RCE via Python Config File Injection in SaveConfigFile() (Interger)_CVE-2026-44888

{
    "lastseen": "",
    "description": "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\u20135 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.",
