Deeper analysis

CVE-2026-37749 is a SQL injection vulnerability (CWE-89) affecting CodeAstro Simple Attendance Management System version 1.0. The flaw resides in the username parameter within the index.php file, enabling remote unauthenticated attackers to bypass authentication mechanisms. It carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity with high impacts across confidentiality, integrity, and availability.

Remote unauthenticated attackers can exploit this vulnerability over the network with low complexity and no user interaction required. By injecting malicious SQL payloads into the username field during login attempts, attackers can bypass authentication entirely, potentially gaining unauthorized access to the system and its functionalities.
