CVE-2026-92221: HospitalManagement SQL Injection Vulnerability

CVE-2026-92221 Overview

CVE-2026-92221 is a SQL injection vulnerability in the open-source gedelumbung/HospitalManagement project. The flaw resides in the generate_index_pasien function within application/models/app_global_admin_model.php. Attackers can manipulate the cari argument to inject arbitrary SQL statements against the backend database. The attack is executable remotely and the exploit has been publicly disclosed. Because the project follows a rolling-release model, no fixed version identifiers exist. The maintainer was notified through an issue report but has not responded, leaving the codebase without an official patch as of publication.

Critical Impact
Authenticated remote attackers can inject SQL through the cari parameter to read, modify, or delete hospital records, including patient data stored in the application database.

Technical Details for CVE-2026-92221

Vulnerability Analysis

The vulnerability is a SQL injection flaw classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The defect exists in generate_index_pasien, a function inside application/models/app_global_admin_model.php used by the administrative search workflow for patient records. The cari parameter — supplied by the client — is concatenated into a SQL query without parameterization or input sanitization. An attacker with access to the admin search interface can therefore alter the query structure and execute attacker-controlled SQL against the underlying database.

Exploitation requires network reach to the application and authenticated access at a privileged level. The impact is bounded to limited confidentiality, integrity, and availability effects on the vulnerable component. Public disclosure of the exploit technique increases the likelihood of opportunistic scanning against exposed HospitalManagement deployments.

Root Cause

The root cause is direct concatenation of untrusted user input into a SQL statement inside generate_index_pasien. The function accepts the cari argument from the request and constructs a search query without using parameter binding provided by the framework's active-record layer. Because rolling releases are used, no version-tagged fix has been shipped.

Attack Vector

An authenticated attacker sends a crafted HTTP request containing a malicious payload in the cari parameter to the admin patient index endpoint. The malicious value breaks out of the intended string context in the SQL query and appends attacker-controlled clauses such as UNION SELECT statements or boolean-based conditions. See the GitHub Issue Tracker and VulDB CVE Entry for technical detail.

Detection Methods for CVE-2026-92221

Indicators of Compromise

HTTP requests to admin patient search endpoints containing SQL metacharacters such as ', --, UNION, or SLEEP( in the cari parameter.
Web server or PHP error logs referencing app_global_admin_model.php and syntax errors near generate_index_pasien.
Unexpected database queries containing INFORMATION_SCHEMA references originating from the HospitalManagement application account.
Anomalous outbound data transfers from the database host following admin search activity.

Detection Strategies

Deploy web application firewall rules that inspect the cari query parameter for common SQL injection payloads.
Enable database query logging and alert on queries containing tautologies, stacked statements, or comment terminators originating from the application user.
Add application-level logging around generate_index_pasien calls to capture the raw input value for forensic review.

Monitoring Recommendations

Monitor authentication logs for privileged admin accounts accessing the patient index feature outside expected hours.
Track spikes in 500-level HTTP responses on admin routes that can indicate injection probing.
Baseline query volume from the HospitalManagement service account and alert on deviations.

How to Mitigate CVE-2026-92221

Immediate Actions Required

Restrict network exposure of the HospitalManagement admin interface to trusted internal networks or VPN users only.
Rotate credentials for any administrative accounts that could reach the vulnerable endpoint.
Review database audit logs for evidence of injection or unauthorized data access since deployment.
Apply a temporary web application firewall rule blocking SQL metacharacters in the cari parameter until code fixes are in place.

Patch Information

No official patch has been released. The maintainer has not responded to the public issue report referenced in the GitHub Issue Tracker. Organizations running this codebase should fork the project and apply a source-level fix that replaces string concatenation with parameterized queries or the framework's active-record bindings in generate_index_pasien. Additional context is available in the VulDB Vulnerability Information.

Workarounds

Remove or disable the generate_index_pasien search feature until a code fix is applied.
Enforce strict server-side input validation, allowing only alphanumeric characters in the cari parameter.
Run the application database under a least-privilege account with no schema-modification rights.
Place the application behind a reverse proxy or WAF that filters SQL injection payloads on admin routes.
