AVideo is a video-sharing Platform. Versions prior to 8.0 contain a SQL Injection vulnerability in the getSqlFromPost() method of Object.php. The $_POST['sort'] array keys are used directly as SQL column identifiers inside an ORDER BY clause.

Although real_escape_string() was applied, it only escapes string-context characters (quotes, null bytes) and provides no protection for SQL identifiers, making it entirely ineffective here. This issue has been fixed in version 8.0. To workaround this issue without upgrading, operators can apply a WAF rule to block POST requests where any sort[*] key contains characters outside [A-Za-z0-9_].

Alternatively, restrict access to the queue view (queue.json.php, index.php) to trusted IP ranges only.
