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
Guardian language-system passes the id GET parameter directly into an unsanitized SQL query in media.php (line 17): SELECT id, filename, extension, type, duration, owner, private FROM files where id = '\".$_GET['id'].\"'. An authenticated attacker can perform error-based SQL injection to extract database contents.

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 · high confidence

The Guardian language-system contains a SQL injection vulnerability in media.php where the 'id' GET parameter is directly concatenated into an unsanitized SQL query. An authenticated attacker can exploit this via error-based SQL injection to extract sensitive database contents.

MitigationReplace the dynamic SQL query with parameterized queries (prepared statements) using PDO or mysqli, and implement proper input validation. Conduct a security audit to identify similar SQL injection vulnerabilities across the application.

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 media.php in the Guardian language-system
    Search for the file media.php within your Guardian language-system installation directory. Common paths may include /media.php or /includes/media.php. Use 'find / -name media.php 2>/dev/null' on Linux or check your web root directory.
    Affected if The file media.php exists in the Guardian language-system installation and handles the 'id' GET parameter.
  2. Inspect the SQL query in media.php line 17
    Open media.php and examine line 17 (or the surrounding lines) where the 'id' GET parameter is used in a SQL query. Look for direct string concatenation like '$id' or $_GET['id'] embedded within the SQL statement without using prepared statements or parameter binding.
    Affected if The code shows direct concatenation of the 'id' parameter into the SQL query without sanitization (e.g., no quotes around the parameter, no mysqli_real_escape_string, no prepared statements).
  3. Verify if authentication is required for the vulnerable endpoint
    Check whether the media.php endpoint is accessible only after authentication. Review the authentication logic at the top of media.php or check if the application requires a valid session/login token to access this page.
    Affected if The vulnerable endpoint is accessible to authenticated users (or is improperly accessible without authentication), allowing them to submit the 'id' parameter.
  4. Confirm the Guardian language-system version
    Check your installed version of the Guardian language-system by reviewing version files, composer.json, or a /version endpoint if available. Compare your version against any documented affected ranges.
    Affected if Your installed version falls within the range of affected versions that contain the vulnerable media.php file with the unsanitized SQL query.
  5. Test for SQL injection via the id parameter
    If you have access to a testing environment, send a benign SQL injection test payload via the 'id' parameter (e.g., id=1' OR '1'='1) to see if the application returns unexpected database errors or altered results. In production, review web server logs for unusual SQL syntax in requests to media.php.
    Affected if The application exhibits SQL injection symptoms such as database errors, unexpected data exposure, or altered query logic when the 'id' parameter contains SQL metacharacters.

You are affected if the Guardian language-system is installed, media.php exists with the unsanitized 'id' parameter in SQL queries at line 17, and the endpoint is accessible to authenticated users (or improperly exposed without auth), allowing SQL injection attacks.
