What is CVE-2026-44887?

CVE-2026-44887 is a critical code injection vulnerability in leiweibau Pi.Alert, published on 27 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

Pi.Alert is a WIFI / LAN intruder detector with web service monitoring. Prior to 2026-05-07, Pi.Alert's web-based configuration editor allows arbitrary Python code to be injected into pialert.conf. Since the background scan daemon loads this file via Python's exec(), injected code executes as the daemon process. With web protection disabled (the default configuration), no authentication is required, making this an unauthenticated Remote Code Execution vulnerability. This vulnerability is fixed in 2026-05-07.

Weakness: CWE-94
