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 vulnerability was found in shafhasan chatbox up to 156a39cde62f78532c3265a70eda12c70907e56f. This impacts an unknown function of the file /chat.php. The manipulation of the argument user_id results in sql injection. The attack may be performed from a remote location. The exploit has been made public and could be used. This product utilizes a rolling release system for continuous delivery, and as such, version information for affected or updated releases is not disclosed.

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

SQL injection vulnerability in shafhasan chatbox /chat.php allows remote attackers to inject malicious SQL commands via the user_id parameter. The vulnerability exists because user-supplied input is not properly sanitized before being used in database queries.

MitigationReplace dynamic SQL queries with parameterized queries or prepared statements in /chat.php to properly handle user input. Implement input validation and use least-privilege database accounts.

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 shafhasan chatbox application
    Search for the file /chat.php in the web root directory or application directory. Common paths may include /var/www/html/, /public_html/, or the application's document root.
    Affected if The file /chat.php exists and is part of a shafhasan chatbox installation.
  2. Verify the application accepts the user_id parameter
    Examine the PHP code in /chat.php to confirm it reads the user_id parameter from GET or POST requests (e.g., $_GET['user_id'] or $_POST['user_id']).
    Affected if The application processes a user_id parameter from user input without validation.
  3. Inspect SQL query construction in chat.php
    Open /chat.php and search for SQL queries that incorporate the user_id parameter directly into the query string (look for concatenations, string interpolation, or direct inclusion of user_id in WHERE clauses).
    Affected if The code contains SQL queries where user_id is appended to the query string without using prepared statements, parameter binding, or escaping functions.
  4. Check database interaction with unsanitized input
    Review all database query functions (mysqli_query, mysql_query, PDO::query, etc.) in chat.php to see if user-supplied user_id values are passed directly as string arguments.
    Affected if Database queries receive the raw user_id value without sanitization, escaping, or parameterized binding.

If /chat.php exists, processes a user_id parameter, and constructs SQL queries by directly embedding that parameter without prepared statements or input sanitization, the environment is affected by this SQL injection vulnerability.
