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 flaw has been discovered in SourceCodester Inventory System 1.0. Affected by this vulnerability is an unknown functionality of the file /Product_Inventory/api/users_handler.php of the component Account Creation Handler. The manipulation of the argument ROLE results in improper authorization. The attack may be performed from remote. The exploit has been released to the public and may be used for attacks.

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

SourceCodester Inventory System 1.0 contains an improper authorization vulnerability in the account creation handler (users_handler.php). Attackers can manipulate the ROLE argument during user registration to assign themselves elevated privileges, bypassing proper authorization checks.

MitigationImplement server-side authorization validation that verifies the requesting user has permission to assign specific roles, and enforce strict allow-listing of permitted role values based on the authenticated user's privileges.

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. Identify if SourceCodester Inventory System is installed
    Look for the application directory containing 'inventory' in the web root, typically in paths like /var/www/html/inventory or C:\xampp\htdocs\inventory. Check for files like index.php, users_handler.php in the application.
    Affected if The SourceCodester Inventory System application is found in the web server's document root
  2. Determine the installed version
    Check version files, README files, or the footer of index.php for version number '1.0'. Also check composer.json or any version config if present in the application root directory.
    Affected if The application version is 1.0 or falls within the affected version range of the inventory system
  3. Verify users_handler.php exists and is accessible
    Locate the users_handler.php file in the application directory, typically under includes/users_handler.php or directly in the application root. Confirm the file is accessible via the web server.
    Affected if The users_handler.php file exists in the application and is web-accessible
  4. Check for role parameter handling in user registration
    Examine the source code of users_handler.php and locate the user registration logic. Search for $_POST or $_GET parameters that handle 'role', 'user_role', or 'role_id' during account creation.
    Affected if The code accepts a role parameter from user input without server-side validation of the requesting user's permissions
  5. Confirm missing authorization checks in role assignment
    Review users_handler.php for authorization logic before role assignment. Look for checks like 'is_admin()', 'check_permission()', or session validation that verifies the current user has rights to assign roles. The vulnerability exists if no such check is found.
    Affected if No server-side authorization validation exists before processing role assignment in the user registration handler

If SourceCodester Inventory System 1.0 is installed with an accessible users_handler.php that accepts role parameters without validating the requesting user's permissions, the environment is affected by CVE-2026-11519.
