CVE-2026-2158
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 detected in code-projects Student Web Portal 1.0. This impacts an unknown function of the file /check_user.php. Performing a manipulation of the argument Username results in sql injection. It is possible to initiate the attack remotely.
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 confidenceA critical SQL injection vulnerability exists in the Student Web Portal 1.0 application. The vulnerability is located in the /check_user.php file where the Username parameter is not properly sanitized before being used in SQL queries, allowing remote attackers to inject malicious SQL code.

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.
-
Confirm Carmelo Student Web Portal installationLocate the web application's root directory and identify if it is the Carmelo Student Web Portal. Check for typical file structures like index.php, login pages, or application-specific files.Affected if The application is Carmelo Student Web Portal and version is 1.0
-
Verify the installed versionCheck the application version number in source files, configuration files, or any version documentation within the web root. Common locations include a README file, version.php, or the main index page footer.Affected if Installed version is exactly 1.0
-
Locate the vulnerable check_user.php fileSearch the web application directory for the file /check_user.php. This file is typically found in the root directory or a includes folder of the web application.Affected if The file check_user.php exists in the application
-
Inspect the Username parameter handlingOpen check_user.php and examine how the Username parameter is processed. Look for SQL query construction that directly incorporates user input without using prepared statements, parameterized queries, or proper sanitization functions.Affected if The code contains direct SQL query concatenation using $_POST['username'], $_GET['username'], or similar user-supplied input without sanitization or parameter binding
-
Determine if the application is network accessibleVerify whether the web server hosting the application is accessible from network locations that could contain remote attackers. Check firewall rules and server exposure settings.Affected if The application is accessible from untrusted networks and the vulnerable code is in use
The environment is affected if Carmelo Student Web Portal version 1.0 is installed, the check_user.php file exists, and the Username parameter is handled in SQL queries without prepared statements or 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 dataReplace dynamic SQL queries with parameterized queries or prepared statements in check_user.php, implement proper input validation and sanitization for all user-supplied parameters, and apply vendor security updates if available.
