Deeper analysis

CVE-2026-6193 is a SQL injection vulnerability (CWE-74, CWE-89) in PHPGurukul Daily Expense Tracking System 1.1. The issue resides in an unknown function within the /register.php file, where manipulation of the email argument triggers the injection.

The vulnerability is remotely exploitable over the network with low attack complexity and no required privileges or user interaction (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L, base score 7.3). Unauthenticated attackers can leverage it to achieve limited impacts on confidentiality, integrity, and availability, such as unauthorized data access or modification.
