The vulnerability CVE-2026-11513 affects itsourcecode Hospital Management System 1.0. It is caused by improper sanitization of the Date parameter in the /adminaccount.php file, allowing an attacker to inject SQL commands remotely. The CVSS 4.0 base score is 5.3, indicating medium severity with network attack vector, low complexity, no privileges required, and no user interaction needed. The vulnerability could potentially allow unauthorized database queries or modifications. No official fix or patch has been published, and the vendor has not released remediation details.

Successful exploitation of this SQL injection vulnerability could allow an attacker to execute arbitrary SQL commands on the backend database. This may lead to unauthorized data access, data modification, or other database-related impacts depending on the database privileges of the web application. However, the CVSS vector indicates low to limited impact on confidentiality, integrity, and availability. No known active exploitation in the wild has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider applying web application firewall (WAF) rules to detect and block SQL injection attempts targeting the Date parameter in /adminaccount.php. Restricting database permissions for the application account may also reduce potential impact. Monitor vendor channels for updates and patches.
