CVE-2026-82914 Overview
CVE-2026-82914 is a SQL injection vulnerability in kishan0725 Hospital-Management-System 1.0. The flaw resides in /search.php, where the Contact parameter is passed to a database query without proper sanitization. Attackers can inject arbitrary SQL statements remotely without authentication. A public exploit has been released, increasing the likelihood of opportunistic attacks against exposed deployments. The vendor was contacted before disclosure but did not respond, and no official patch is currently available. The vulnerability is categorized under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).
Critical Impact
Unauthenticated remote attackers can inject SQL commands through the Contact parameter in /search.php, potentially exposing patient records, credentials, and other sensitive database contents.
Affected Products
- kishan0725 Hospital-Management-System version 1.0
- The /search.php endpoint of the application
- The Contact request parameter handled by the search functionality

Technical Details for CVE-2026-82914
Vulnerability Analysis
The vulnerability affects the search functionality of the Hospital-Management-System application. The /search.php script accepts a Contact parameter from user input and concatenates it directly into an SQL query. Because the input is neither parameterized nor escaped, attackers can break out of the intended query context and append arbitrary SQL clauses. The application executes the resulting statement against the backing database with the privileges of the web application's database user. Successful exploitation permits attackers to read, modify, or delete records, and depending on database configuration, may enable file operations or command execution through database features.
Root Cause
The root cause is improper neutralization of special elements passed to a downstream SQL interpreter [CWE-74]. The Contact argument is embedded into a query string without prepared statements or input validation, allowing metacharacters such as single quotes, semicolons, and SQL keywords to alter query semantics.
Attack Vector
Exploitation is remote and requires no authentication or user interaction. An attacker sends a crafted HTTP request to /search.php with a malicious Contact parameter value. Because a public exploit exists, automated scanners and low-skill attackers can weaponize the flaw against internet-exposed instances of the Hospital-Management-System.
No verified proof-of-concept code is included here. Refer to the VulDB entry for CVE-2026-82914 and the VulDB vulnerability record #397291 for technical details and exploit references.
Detection Methods for CVE-2026-82914
Indicators of Compromise
- HTTP requests to /search.php containing SQL metacharacters such as ', --, UNION, SELECT, or SLEEP( in the Contact parameter.
- Unexpected database errors or long response times originating from the search endpoint, indicating time-based or error-based injection attempts.
- Web server access logs showing repeated /search.php requests from a single source with varying Contact values.
Detection Strategies
- Deploy web application firewall (WAF) signatures targeting SQL injection patterns on the Contact parameter of /search.php.
- Enable database query logging and alert on anomalous query structures such as stacked statements or unusual UNION SELECT patterns.
- Correlate web access logs with database audit trails to identify injected payloads that reached the database engine.
Monitoring Recommendations
- Monitor outbound traffic from the application server for data exfiltration following suspicious search requests.
- Track authentication and privileged-account activity on the backing database to detect post-exploitation credential abuse.
- Alert on new administrative accounts or schema modifications within the Hospital-Management-System database.
How to Mitigate CVE-2026-82914
Immediate Actions Required
- Restrict access to the Hospital-Management-System application, placing it behind VPN or IP allowlists until a fix is in place.
- Deploy WAF rules that block SQL metacharacters in the Contact parameter of /search.php.
- Review web server and database logs for evidence of prior exploitation and rotate credentials if compromise is suspected.
Patch Information
The vendor did not respond to disclosure, and no official patch is available at the time of publication. Operators should apply source-code fixes locally by replacing string concatenation in /search.php with parameterized queries or prepared statements using PDO or mysqli bound parameters. Input validation should reject non-numeric or unexpected characters in the Contact field.
Workarounds
- Disable or remove the /search.php endpoint if it is not required for operations.
- Apply an application-layer filter that enforces a strict allowlist on the Contact parameter, such as digits and limited punctuation only.
- Run the database account used by the application with the minimum privileges required, removing FILE, CREATE, and DROP where possible to limit exploitation impact.
