CVE-2026-14659: SQL Injection in itsourcecode Hospital Management System 1.0

Technical summary

CVE-2026-14659 is a SQL injection flaw (CWE-89, CWE-74) in Hospital Management System 1.0's /patientappointment.php endpoint. The application fails to properly sanitize or parameterize the 'patiente' input parameter, allowing SQL commands to be embedded in HTTP requests. An authenticated user can manipulate this parameter to execute arbitrary SQL queries against the backend database. The CVSS 3.1 score of 6.3 (Medium severity) reflects the requirement for prior authentication (PR:L), though the impact spans confidentiality, integrity, and availability of patient data.

Business impact

Healthcare facilities using this system face exposure of sensitive patient health information, appointment records, and potentially billing data. An insider threat or compromised staff account could alter or delete critical appointment schedules, disrupting patient care delivery. Regulatory implications include HIPAA violations (in the US) and data protection law non-compliance depending on jurisdiction. Reputational damage and liability for unauthorized data access are significant secondary risks.

Affected systems

itsourcecode Hospital Management System version 1.0 is the only confirmed affected version. Organizations running this software on Internet-facing servers or within networks accessible to authenticated users are at risk. The vulnerability does not appear in the vendor product documentation provided; verify your deployment version against itsourcecode's official release notes.

Exploitability

The vulnerability is readily exploitable for attackers with valid credentials. Proof-of-concept code is publicly disclosed, lowering the barrier to exploitation. An attacker needs network access to the application and authentication credentials—either through compromise of a staff account, weak password enforcement, or insider access. No special tools beyond a standard HTTP client are required to craft and send malicious SQL payloads. The vulnerability is not currently listed in CISA's Known Exploited Vulnerabilities (KEV) catalog.

Remediation

Immediately update itsourcecode Hospital Management System to a patched version confirmed by the vendor to address this SQL injection. As an interim control, restrict network access to the application to trusted internal networks only and enforce strong authentication policies. Parameterized queries and prepared statements must be implemented across all user input handling. Conduct a security audit of the application code for similar SQL injection points.

Patch guidance

Contact itsourcecode directly or visit their official advisory page for patched version availability and deployment instructions. Verify patch version numbers against the vendor's security advisory before applying updates. Test patches in a non-production environment first, given the critical nature of hospital management systems. Prioritize patching based on the scope of authenticated users who have access to the /patientappointment.php endpoint.

Detection guidance

Monitor access logs for the /patientappointment.php endpoint for suspicious patterns—requests with SQL keywords (SELECT, UNION, DROP, INSERT, UPDATE, DELETE) in the patiente parameter, unusual character encoding, or repeated failed queries. Deploy Web Application Firewall (WAF) rules to block common SQL injection signatures. Enable database query logging and alert on unexpected or malformed SQL statements. Review staff access patterns to the patient appointment module for anomalies coinciding with the vulnerability disclosure date.

Why prioritize this

Although assigned a Medium severity score, this vulnerability affects protected health information and critical healthcare operations, elevating its operational priority. Public disclosure of proof-of-concept code increases short-term exploitation likelihood. The authentication requirement provides some defense but does not eliminate risk from insider threats or credential compromise. Organizations should treat this as high-priority for remediation despite the CVSS score.

Risk score, explained

The CVSS 3.1 score of 6.3 reflects a vulnerability that can be exploited remotely over the network (AV:N) with low complexity (AC:L), but requires a logged-in user (PR:L). The lack of user interaction (UI:N) means exploitation can be automated. Impact is assessed as low across confidentiality, integrity, and availability (C:L/I:L/A:L)—reflecting that the attacker has limited scope and cannot compromise the entire system. The Medium rating appropriately balances the authentication barrier against the sensitivity of healthcare data and public availability of exploit code.
