CVE-2026-39110

The vulnerability is a SQL injection flaw in the contactno parameter of the forgot-password.php page in Apartment Visitors Management System v1.1 [1]. The root cause is improper input validation and unsafe handling of user-supplied data, allowing an attacker to inject arbitrary SQL commands into backend queries [2].

An unauthenticated attacker can exploit this by sending a crafted HTTP request to the forgot-password endpoint with malicious SQL payloads in the contactno parameter. No authentication or special privileges are required, making the attack surface broad and easily accessible from the network [2].

Successful exploitation enables the attacker to manipulate the SQL query to retrieve sensitive database contents, such as user credentials, personal information, or other stored data. The impact includes unauthorized data disclosure and potential further compromise of the application [2].

As of the advisory, no official patch has been released. Mitigation requires implementing prepared statements (parameterized queries) and rigorous input validation for all user-supplied parameters, following OWASP secure coding practices [2].
