Quick assessment

Affected
leiweibau Pi.Alert
Exploitation
Public or AI PoC available; prioritize validation
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Pi.Alert是jokob-sk个人开发者的一款 WIFI / LAN 入侵检测器。 Pi.Alert 2026-05-07之前版本存在代码注入漏洞，该漏洞源于SaveConfigFile()端点将用户提供的数字配置值直接写入pialert.conf文件而未经验证，且该文件通过Python的exec()加载，可能导致未认证的远程代码执行攻击。

Vulnerability Title
Unauthenticated RCE via Python Config File Injection in SaveConfigFile() (Interger)
Source: CVE Program / CVE List V5
Vulnerability 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 pialert.conf without validation. Since pialert.conf is loaded via Python's exec() every 3–5 minutes by the background cron process, an attacker can inject arbitrary Python code and achieve unauthenticated OS-level RCE. On default installations (PIALERT_WEB_PROTECTION = False), no credentials are required. This vulnerability is fixed in 2026-05-07.
