CVE-2026-14730 Overview
CVE-2026-14730 is a SQL injection vulnerability in itsourcecode Hospital Management System 1.0. The flaw resides in the /patientprofile.php script, where the patientname parameter is passed to a database query without proper sanitization. Attackers can manipulate this parameter to inject arbitrary SQL statements. The vulnerability is remotely exploitable and requires only low-privileged authenticated access. Public exploit code has been released, increasing the likelihood of opportunistic attacks against exposed installations. The weakness is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).
Critical Impact
Remote attackers with low privileges can inject SQL commands through the patientname parameter, potentially exposing patient records, credentials, and other sensitive database contents.
Affected Products
- itsourcecode Hospital Management System 1.0

Technical Details for CVE-2026-14730
Vulnerability Analysis
The vulnerability exists in the patient profile handling logic of itsourcecode Hospital Management System 1.0. The /patientprofile.php endpoint accepts a patientname parameter and concatenates it into a SQL query without parameterization or input validation. This allows an attacker to break out of the intended query context and append or modify SQL clauses.
Successful exploitation can lead to unauthorized data retrieval, modification of database records, or authentication bypass depending on the underlying query. The public disclosure includes proof-of-concept details, lowering the barrier for exploitation against internet-facing deployments.
Root Cause
The root cause is improper neutralization of user-supplied input passed to a downstream SQL interpreter [CWE-74]. The application constructs SQL statements through string concatenation rather than using prepared statements with bound parameters. Any special SQL characters submitted via the patientname argument are executed as part of the query.
Attack Vector
Exploitation occurs over the network against the PHP endpoint. An authenticated user with low privileges submits a crafted HTTP request containing SQL metacharacters in the patientname parameter. The injected payload is interpreted by the backend database, allowing attackers to enumerate schemas, extract sensitive data, or manipulate application state. Refer to the VulDB CVE-2026-14730 entry and the GitHub Issue Discussion for technical details.
Detection Methods for CVE-2026-14730
Indicators of Compromise
- HTTP requests to /patientprofile.php containing SQL metacharacters such as single quotes, UNION SELECT, --, or OR 1=1 in the patientname parameter.
- Unexpected database error messages or extended query execution times originating from the patient profile endpoint.
- Application or web server logs showing anomalous access patterns to /patientprofile.php from a single source.
Detection Strategies
- Enable verbose access logging on the web server and search for suspicious patientname values containing SQL syntax.
- Deploy a web application firewall (WAF) with SQL injection signatures inspecting query strings and POST bodies for /patientprofile.php.
- Correlate authentication events with subsequent injection attempts to identify compromised low-privileged accounts.
Monitoring Recommendations
- Monitor database audit logs for unusual queries referencing system tables such as information_schema or mysql.user.
- Alert on repeated HTTP 500 responses or database errors emitted from /patientprofile.php.
- Track outbound data volumes from the database server to identify potential large-scale record extraction.
How to Mitigate CVE-2026-14730
Immediate Actions Required
- Restrict network access to the Hospital Management System, placing it behind VPN or IP allowlists until a patch is applied.
- Deploy WAF rules that block SQL injection payloads targeting the patientname parameter on /patientprofile.php.
- Rotate database credentials and audit patient records for unauthorized access or modification.
Patch Information
No official vendor patch has been referenced in the available advisories. Consult the IT Source Code Resource and the VulDB Vulnerability #376312 entry for updates. Until a fix is released, administrators should apply source-level remediation by replacing string concatenation with prepared statements and parameter binding in /patientprofile.php.
Workarounds
- Modify /patientprofile.php to use parameterized queries or an ORM layer that safely handles input.
- Apply strict server-side input validation on patientname, rejecting characters outside an alphanumeric allowlist.
- Enforce least-privilege database accounts so the web application cannot access or modify tables beyond its functional scope.
- Disable verbose database error messages in production to limit information leakage during injection attempts.
