CVE-2026-11514: SQL Injection in itsourcecode Hospital Management System 1.0

Technical summary

CVE-2026-11514 is a SQL injection flaw (CWE-89, CWE-74) in the /addpatient.php endpoint of itsourcecode Hospital Management System 1.0. The 'admissiontme' parameter fails to properly sanitize or parameterize user input before passing it to a database query. An authenticated user can craft a specially formatted value to break out of the intended query context and execute arbitrary SQL. The vulnerability affects data confidentiality, integrity, and availability within the application's database scope.

Business impact

Compromise of a hospital management system creates direct operational and regulatory risk. Patient records could be accessed, modified, or deleted by attackers with valid login credentials. This threatens patient privacy (HIPAA implications in US healthcare), clinical workflow continuity, and data integrity—critical concerns in any healthcare facility. The presence of a published exploit increases attack likelihood, making this a priority remediation target despite the requirement for authenticated access.

Affected systems

itsourcecode Hospital Management System version 1.0 is confirmed vulnerable. No version information is currently available to indicate whether earlier or later releases are affected; organizations must consult the vendor's advisory to determine their specific exposure.

Exploitability

The vulnerability is remotely exploitable but requires valid application login credentials (CVSS PR:L), limiting the attack surface to authorized or compromised users. However, a published exploit exists, meaning the technical barriers to exploitation are significantly lowered. An attacker already possessing staff credentials or who has compromised an account can leverage this flaw without specialized skill or tools.

Remediation

Obtain and apply a patched version from itsourcecode once available. In the interim, implement input validation on the 'admissiontme' parameter to reject or escape SQL metacharacters, enforce parameterized queries (prepared statements) in the affected script, and restrict database user privileges to the minimum necessary. Monitor access logs for unusual query patterns or failed SQL syntax errors.

Patch guidance

Contact itsourcecode for a security update addressing the SQL injection in /addpatient.php. Verify patch availability and compatibility with your deployment before applying. Test updates in a non-production environment to ensure no regression in clinical workflows or integrations. Document patch version and deployment date for compliance audits.

Detection guidance

Monitor for SQL error messages or unusual query behavior in application logs tied to the /addpatient.php endpoint. Search logs for common SQL injection payloads (UNION, DECLARE, xp_cmdshell, etc.) in the 'admissiontme' parameter. Implement Web Application Firewall (WAF) rules to block SQL keywords and syntax in admission form submissions. Database query logging can reveal successful injections through unexpected table or schema access.

Why prioritize this

Although this vulnerability requires authentication, the presence of a published exploit, combined with the critical nature of healthcare data, justifies urgent prioritization. Hospital staff turnover, credential sharing, and phishing create pathways to compromise valid accounts. The direct impact on patient data and system integrity places this in the 'address within weeks' category for healthcare deployments.

Risk score, explained

The CVSS 3.1 score of 6.3 (MEDIUM) reflects the authentication requirement (PR:L) and attack complexity factors that limit the attack surface compared to unauthenticated flaws. However, the integrity and confidentiality impacts on patient data, combined with published exploit availability, elevate practical risk beyond the base score. Healthcare organizations should treat this as a high-priority vulnerability due to regulatory and operational context.
