CVE-2026-75086 Overview
CVE-2026-75086 is a SQL injection vulnerability in itsourcecode Hospital Management System 1.0. The flaw exists in /viewroom.php, where the delid parameter is passed to a database query without proper sanitization. Attackers can manipulate the delid argument to inject arbitrary SQL statements. The vulnerability is remotely exploitable and requires only low-privileged authentication. Public disclosure of the exploit technique has occurred, increasing the risk of opportunistic attacks against exposed installations. The weakness is categorized under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).
Critical Impact
Authenticated remote attackers can inject SQL through the delid parameter of /viewroom.php, potentially exposing or modifying hospital records stored in the backend database.

Technical Details for CVE-2026-75086
Vulnerability Analysis
The vulnerability resides in the room management workflow of itsourcecode Hospital Management System 1.0. The /viewroom.php script accepts a delid parameter intended to identify a room record for deletion. The application concatenates this parameter directly into an SQL statement without parameterization or input validation. An attacker who can reach the endpoint can substitute the expected integer identifier with SQL syntax. The database engine then interprets and executes the injected payload alongside the intended query.
Exploitation does not require complex tooling. Standard SQL injection techniques such as UNION-based extraction, boolean-based blind inference, and time-based blind queries all apply. The impact scope covers confidentiality, integrity, and availability of the backing database, though the CVSS 4.0 vector rates each as low. Public exploit disclosure means detection engineering should assume opportunistic scanning.
Root Cause
The root cause is improper neutralization of user-supplied input passed to a downstream SQL interpreter [CWE-74]. The delid parameter is trusted as a numeric identifier but is not cast, validated, or bound as a prepared statement parameter. This pattern is common in legacy PHP applications that use direct string concatenation with mysqli_query() or similar functions.
Attack Vector
The attack vector is network-based over HTTP or HTTPS to the affected /viewroom.php endpoint. An attacker submits a crafted request such as a GET or POST containing a malicious delid value. Because low-level privileges are required, the attacker must first obtain valid application credentials or reuse a session. Once authenticated, the attacker manipulates delid to append conditional payloads, subqueries, or stacked statements depending on the database driver configuration.
No verified proof-of-concept code is published in a curated exploit database. Technical write-ups are referenced through the GitHub Issue Tracker and VulDB entry for CVE-2026-75086.
Detection Methods for CVE-2026-75086
Indicators of Compromise
- HTTP requests to /viewroom.php where the delid parameter contains SQL metacharacters such as single quotes, UNION, SELECT, SLEEP(, or comment sequences like -- and #.
- Database error messages returned in HTTP responses referencing mysqli or SQL syntax errors originating from /viewroom.php.
- Unusually long or URL-encoded delid values in web server access logs.
Detection Strategies
- Deploy web application firewall signatures that inspect the delid parameter for SQL injection patterns on requests to /viewroom.php.
- Correlate authenticated session activity with anomalous query patterns against the hospital management database, such as bursts of SELECT operations following a delid request.
- Enable database query logging and alert on statements referencing information_schema or unexpected UNION clauses originating from the web application service account.
Monitoring Recommendations
- Forward web server, application, and database logs to a centralized analytics platform for correlation across the request path.
- Baseline normal delid values as integers and alert on any deviation containing non-numeric characters.
- Monitor outbound connections from the database host, as post-exploitation activity may include data exfiltration.
How to Mitigate CVE-2026-75086
Immediate Actions Required
- Restrict network access to the Hospital Management System to trusted management networks or VPN clients until a fix is applied.
- Audit application accounts and revoke unused low-privilege credentials that could be used to reach the vulnerable endpoint.
- Review database and web server logs for prior exploitation attempts referencing /viewroom.php and the delid parameter.
Patch Information
No vendor patch is referenced in the NVD entry at the time of publication. Administrators should monitor the IT Source Code project site and the GitHub Issue Tracker for a fix. In the interim, apply the source-level workarounds described below.
Workarounds
- Modify /viewroom.php to cast delid to an integer using intval() before use in the SQL statement, or replace the query with a prepared statement using mysqli or PDO parameter binding.
- Deploy a web application firewall rule that blocks non-numeric values in the delid query parameter.
- Enforce least privilege on the database account used by the application, removing DROP, ALTER, and cross-database SELECT permissions where possible.
# Example ModSecurity rule to block non-numeric delid values on /viewroom.php
SecRule REQUEST_URI "@streq /viewroom.php" \
"chain,phase:2,deny,status:400,id:1075086,msg:'CVE-2026-75086 SQLi attempt on delid'"
SecRule ARGS:delid "!@rx ^[0-9]+$" "t:none"
