CVE-2026-75087 Overview
CVE-2026-75087 is a SQL injection vulnerability in itsourcecode Hospital Management System 1.0. The flaw resides in the /viewdepartment.php script, where the delid parameter is passed to a backend SQL query without sanitization. Remote attackers with low-privilege access can manipulate the parameter to alter query logic. The exploit has been publicly disclosed, increasing the likelihood of opportunistic attacks against exposed installations. The vulnerability is tracked under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).
Critical Impact
Authenticated remote attackers can inject arbitrary SQL through the delid parameter of /viewdepartment.php, potentially exposing or altering hospital records stored in the backend database.
Affected Products
- itsourcecode Hospital Management System 1.0
- Deployments hosting /viewdepartment.php with the vulnerable delid handler
- Downstream forks or derivative PHP applications reusing the same query logic

Technical Details for CVE-2026-75087
Vulnerability Analysis
The vulnerability affects the department management workflow of itsourcecode Hospital Management System 1.0. When a user issues a delete request against /viewdepartment.php, the application reads the delid argument from the HTTP request and concatenates it into a SQL statement. Because the parameter is neither type-cast nor bound as a prepared statement placeholder, an attacker can inject additional SQL syntax. A successful attack allows the adversary to read arbitrary database rows, modify records, or execute stacked queries depending on database privileges. Public disclosure of the exploit lowers the technical barrier for reuse against exposed instances.
Root Cause
The root cause is improper neutralization of user-supplied input before use in a SQL query. The delid argument is trusted as an integer identifier but never validated or parameterized, matching the [CWE-74] injection pattern.
Attack Vector
Exploitation is remote and requires only low privileges within the application. An attacker submits a crafted delid value to /viewdepartment.php, typically via URL query string, and observes database behavior or extracts data through boolean, error-based, or time-based techniques. No user interaction is required beyond the attacker's own authenticated session.
No verified proof-of-concept code is bundled with this advisory. Public technical details are available on the VulDB entry for CVE-2026-75087 and the associated GitHub issue.
Detection Methods for CVE-2026-75087
Indicators of Compromise
- HTTP requests to /viewdepartment.php containing SQL metacharacters such as single quotes, UNION, SLEEP(, or comment sequences in the delid parameter.
- Web server access logs showing repeated delid values with non-numeric payloads originating from a single source IP.
- Unexpected database errors, prolonged query execution times, or unauthorized SELECT/DROP activity in MySQL logs.
Detection Strategies
- Deploy web application firewall rules that inspect the delid parameter and block requests containing SQL syntax tokens.
- Enable database query logging and alert on multiple failed queries or queries touching schema metadata tables such as information_schema.
- Correlate authentication events with high-volume access to /viewdepartment.php to identify abusive low-privilege accounts.
Monitoring Recommendations
- Baseline normal request patterns for hospital management endpoints and flag deviations in parameter shape or length.
- Forward web and database logs to a centralized analytics platform for cross-source correlation and retention.
- Review privileged database account activity daily until the application is patched or replaced.
How to Mitigate CVE-2026-75087
Immediate Actions Required
- Restrict network access to the Hospital Management System so that only trusted clinical networks can reach /viewdepartment.php.
- Audit application user accounts and revoke any low-privilege accounts that are not strictly required.
- Rotate database credentials used by the application and enforce least privilege on the associated database user.
Patch Information
No vendor patch is referenced in the NVD entry at the time of publication. Operators should monitor the itsourcecode homepage and the VulDB advisory for fix availability. Until an official patch is released, apply source-level mitigations: replace string concatenation in the delid query with a parameterized statement and cast the identifier to an integer before use.
Workarounds
- Add a reverse proxy or web application firewall rule that rejects non-numeric delid values before they reach PHP.
- Modify /viewdepartment.php to use intval($_GET['delid']) or prepared statements with bound parameters.
- Temporarily disable the department deletion feature if it is not required for daily operations.
