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 · unedited
A security vulnerability has been detected in Kushan2k student-management-system up to f16a4ceaddd6729c4b306ed4641cda3176c1ef2a. Affected by this issue is the function edit-admin of the file controllers/AdminController.php of the component Profile Update Endpoint. The manipulation of the argument isadmin leads to improper authorization. Remote exploitation of the attack is possible. The exploit has been disclosed publicly and may be used. This product follows a rolling release approach for continuous delivery, so version details for affected or updated releases are not provided. The project was informed of the problem early through an issue report but has not responded yet.

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 confidence

The edit-admin function in controllers/AdminController.php of the Kushan2k student-management-system suffers from an improper authorization vulnerability. The isadmin parameter can be manipulated during profile updates, allowing privilege escalation where a user could potentially grant themselves administrative privileges. This is a classic Broken Access Control / Insecure Direct Object Reference issue.

MitigationImplement server-side authorization checks to verify the requesting user has proper admin privileges before allowing profile modifications. The isadmin parameter should be validated against the current user's actual role, not accepted from client input. Consider implementing role-based access control (RBAC) with proper session validation.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Locate the Kushan2k student-management-system installation
    Search the server for AdminController.php file, typically found in application/controllers/ or similar MVC paths
    Affected if The file AdminController.php exists in the application
  2. Verify the edit-admin function exists in AdminController.php
    Open AdminController.php and locate the edit-admin or editAdmin function definition
    Affected if The edit-admin function exists in AdminController.php and processes the isadmin parameter
  3. Check if isadmin parameter is processed without role validation
    Examine the edit-admin function code to see if it validates the requesting user's role before allowing modification of the isadmin parameter
    Affected if The isadmin parameter is accepted and processed without verifying the current user has admin privileges
  4. Test if the Profile Update Endpoint accepts isadmin parameter manipulation
    Send a Profile Update request to the edit-admin endpoint with isadmin=1 or isadmin=true while logged in as a non-admin user
    Affected if The request succeeds and the user's admin status is modified without proper authorization
  5. Review user role permission checks in the function
    Search the edit-admin function for role-based access control (RBAC) checks, such as checking if the user is_admin, has_permission, or isAuthorized before allowing isadmin parameter updates
    Affected if No authorization check exists before allowing modification of the isadmin parameter

If the Kushan2k student-management-system is installed and the edit-admin function allows manipulation of the isadmin parameter without verifying the requesting user's admin privileges, the environment is affected by CVE-2026-11476.

Mitigation

Implement server-side authorization checks to verify the requesting user has proper admin privileges before allowing profile modifications. The isadmin parameter should be validated against the current user's actual role, not accepted from client input.
