Unauthenticated SQLi in Apartment Visitors Management System
The National Vulnerability Database has disclosed CVE-2026-39111, a critical SQL Injection vulnerability in Apartment Visitors Management System V1.1. This flaw exists in the email parameter of the forgot-password.php page, allowing unauthenticated attackers to manipulate backend SQL queries.
This vulnerability carries a CVSS score of 7.5 (HIGH), underscoring the severe risk it poses. Attackers can exploit this without any prior authentication, leading directly to the retrieval of sensitive user data from the system’s database. The impact is significant, as it grants direct access to confidential information.
For defenders, this is a clear call to action. Any organization utilizing Apartment Visitors Management System V1.1 or similar PHP-based visitor management solutions must immediately verify their exposure. SQL Injection remains a top vector for data exfiltration, and an unauthenticated entry point means the attacker’s calculus is simple: find and exploit.
