Deeper analysis

CVE-2026-3708 is a SQL injection vulnerability (CWE-74, CWE-89) in code-projects Simple Flight Ticket Booking System 1.0. The flaw resides in an unknown function within the file /login.php, where manipulation of the Username argument triggers the injection.

Remote attackers can exploit this vulnerability without authentication privileges, user interaction, or high complexity, requiring only network access. Exploitation enables limited impacts on confidentiality, integrity, and availability, as reflected in its CVSS score of 7.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L). A public exploit is available for use in attacks.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation of all inputs (including the Username argument to login.php) to reject malformed or malicious data that enables SQL injection.

prevent

Enforces access-control decisions so that unauthenticated or improperly validated requests cannot reach or bypass the login function.

prevent

Requires timely remediation of the publicly disclosed flaw in /login.php before exploitation occurs.
