CVE-2026-13520
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability was determined in itsourcecode Hospital Management System 1.0. Affected is an unknown function of the file /appointmentapproval.php of the component Appointment Handler. This manipulation of the argument editid causes sql injection. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe itsourcecode Hospital Management System 1.0 contains a SQL injection vulnerability in the /appointmentapproval.php file within the Appointment Handler component. The 'editid' parameter is not properly sanitized before being used in SQL queries, allowing remote attackers to inject malicious SQL code. This could enable unauthorized data access, modification, or potentially remote code execution depending on database configuration.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the Hospital Management System installationSearch for appointmentapproval.php in the web server's document root directories (/var/www/html, /www, or C:\inetpub\wwwroot on Windows). Also check subdirectories like /hospital/ or /hms/Affected if The file appointmentapproval.php exists in the application's web-accessible directory
-
Verify the application versionCheck for version files in the application root such as version.php, version.txt, README.txt, or examine the main index.php for version metadata indicating version 1.0Affected if The installed version is itsourcecode Hospital Management System 1.0
-
Inspect the editid parameter in appointmentapproval.phpOpen appointmentapproval.php and locate code handling the 'editid' parameter (via $_GET or $_POST). Examine whether this parameter is used in SQL queries with prepared statements, parameter binding, or escaping functionsAffected if The 'editid' parameter is directly concatenated into SQL queries without sanitization, prepared statements, or parameter binding
You are affected if you are running itsourcecode Hospital Management System version 1.0 and the appointmentapproval.php file uses the 'editid' parameter directly in SQL queries without parameterized queries or input sanitization.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement parameterized queries or prepared statements for all database operations involving user-supplied input, particularly the editid parameter in appointmentapproval.php. Additionally, apply input validation and employ least-privilege database accounts to limit the impact of any successful SQL injection.
