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
The Ebook Downloader plugin for WordPress is vulnerable to SQL Injection via the 'download' parameter in all versions up to, and including, 1.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

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 Ebook Downloader WordPress plugin fails to properly escape the user-supplied 'download' parameter and lacks prepared statements in its SQL queries. This allows unauthenticated attackers to inject arbitrary SQL commands via the download parameter to extract sensitive data from the database.

MitigationUpdate to a patched version of the plugin if available; otherwise disable the plugin until a fix is released. Consider deploying a WAF rule to block SQL injection attempts as a temporary mitigation.

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. Confirm plugin installation and version
    Navigate to WordPress Admin > Plugins and locate 'Infoway Ebook Downloader' or check the plugin directory /wp-content/plugins/ for an ebook-downloader folder. View the plugin header to read the installed version number.
    Affected if The plugin is installed and the version is 1.0 or below.
  2. Identify the vulnerable file
    Locate the main plugin PHP file (commonly index.php or ebook-downloader.php in the plugin folder) and search for code handling the 'download' parameter and direct SQL queries without prepare() statements.
    Affected if The plugin file contains a 'download' parameter processed with unsanitized variables in SQL queries.
  3. Check if the vulnerable endpoint is accessible
    Send a test request to the affected page (typically the page where the download shortcode is placed) including a 'download' parameter with a simple test value (e.g., ?download=1). Use a Web Application Firewall or HTTP traffic logs to verify the request reaches the plugin.
    Affected if The page responds and the plugin processes the 'download' parameter without requiring authentication.
  4. Review access logs for exploitation signs
    Examine web server access logs (Apache/nginx) for requests to pages using this plugin that contain SQL injection patterns in the 'download' parameter (e.g., UNION SELECT, OR 1=1, etc.).
    Affected if Log entries show SQL injection payloads submitted to the 'download' parameter.

Your environment is affected if the Infoway Ebook Downloader plugin version 1.0 or below is installed and the download functionality is accessible to unauthenticated users.
