CVE-2026-102845 Overview
CVE-2026-102845 is an information disclosure vulnerability affecting the gedelumbung HospitalManagement application through commit c2d45543789a3887067d3915f69d44cfc2cf76a8. The flaw resides in the error_reporting function within index.php and impacts the HTTP Response component. Remote attackers can trigger the issue over the network without authentication and receive sensitive application data through error messages. The exploit has been publicly disclosed, increasing the risk of opportunistic abuse. Because the project follows a rolling release model, no fixed version identifier is available, and the maintainer has not responded to the reported issue.
Critical Impact
Remote, unauthenticated attackers can extract sensitive application details through verbose error responses, aiding follow-on attacks against the HospitalManagement application.
Affected Products

- Codebase up to commit c2d45543789a3887067d3915f69d44cfc2cf76a8
- index.php HTTP Response component using error_reporting

Technical Details for CVE-2026-102845
Vulnerability Analysis
The vulnerability is an information disclosure weakness [CWE-200] triggered through the application's HTTP response handling. The error_reporting call in index.php leaves verbose PHP error reporting enabled in a production context. When an attacker submits crafted or malformed requests, the resulting HTTP responses reveal internal application details such as file paths, function names, database queries, or stack context. This information supports reconnaissance for follow-on attacks, including injection, authentication bypass, and file inclusion attempts. The issue is network-reachable and requires no authentication or user interaction.
Root Cause
The root cause is insecure use of PHP's error_reporting directive in the entry point index.php. The application emits diagnostic output intended for development directly to clients through HTTP responses. Sensitive runtime details that should be logged internally instead surface in the response body.
Attack Vector
An attacker interacts with the HospitalManagement application over HTTP and induces error conditions by sending malformed parameters, invalid values, or requests to non-existent routes. The server responds with verbose PHP errors that expose implementation details. No credentials or user interaction are required, and the technique can be automated at scale.
No verified proof-of-concept code is available. Technical details are documented in the GitHub Issue #11 Discussion and the VulDB CVE-2026-102845 entry.
Detection Methods for CVE-2026-102845
Indicators of Compromise
- HTTP responses from the HospitalManagement application containing PHP warnings, notices, or fatal error strings such as Warning:, Notice:, Fatal error:, or Stack trace:.
- Unusual volumes of malformed GET or POST requests targeting index.php from a single source address.
- Response bodies leaking absolute filesystem paths, SQL fragments, or internal function names.
Detection Strategies
- Inspect outbound HTTP responses at the web server or reverse proxy for PHP error signatures and block or alert on matches.
- Correlate 4xx and 5xx response bursts with request payloads that include unexpected data types to identify reconnaissance activity.
- Review application access logs for repeated requests to index.php with parameter fuzzing patterns.
Monitoring Recommendations
- Enable web application firewall (WAF) rules to flag responses that contain PHP error keywords.
- Forward web server, application, and PHP error logs to a centralized analytics platform for continuous review.
- Alert on any production request that returns a response containing stack traces or file path disclosures.
How to Mitigate CVE-2026-102845
Immediate Actions Required
- Disable verbose error output in production by setting display_errors = Off and display_startup_errors = Off in php.ini.
- Remove or reduce the error_reporting level in index.php and route errors to a private log file using log_errors = On.
- Place the application behind a reverse proxy or WAF that strips or rewrites error responses containing sensitive information.
Patch Information
No vendor patch is available. The maintainer of gedelumbung HospitalManagement has not responded to the reported issue, and the project uses a rolling release model without fixed version identifiers. Track the GitHub Hospital Management Repo and the GitHub Issue #11 Discussion for updates.
Workarounds
- Override PHP error configuration at the server level using .htaccess or virtual host directives to suppress client-facing errors.
- Deploy a custom error handler in the application that returns generic HTTP 500 responses without stack information.
- Restrict access to the HospitalManagement application to trusted networks or VPN clients until a fix is issued.
# Configuration example: disable client-visible PHP errors
# Add to php.ini or a per-site configuration
display_errors = Off
display_startup_errors = Off
log_errors = On
error_log = /var/log/php/hospitalmanagement_error.log
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
