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

A blind SQL injection vulnerability exists in the shiptrack Booking Calendar and Notification plugin (versions <= 4.0.3). The vulnerability allows unauthenticated attackers to inject malicious SQL queries through unsanitized user input, potentially enabling data exfiltration from the database or further compromise of the affected system.

MitigationUpgrade to a patched version of the Booking Calendar and Notification plugin as soon as one becomes available. If no patch is available, disable the plugin until a fix is released.

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 shiptrack Booking Calendar plugin
    Access your WordPress admin dashboard, navigate to Plugins, and search for 'shiptrack Booking Calendar and Notification' in the installed plugins list. Note the version number displayed next to the plugin name.
    Affected if The plugin is installed and the version shown is 4.0.3 or lower
  2. Verify the plugin files exist
    Check the wp-content/plugins directory for a folder named 'shiptrack-booking-calendar' or similar. Examine the main plugin file (usually named main.php, shiptrack.php, or index.php) within that folder for the version declaration.
    Affected if The plugin files exist and the hardcoded version in the plugin header reads 4.0.3 or below
  3. Confirm booking calendar functionality is active
    Visit the frontend of your WordPress site where the booking calendar shortcode or widget is embedded. Common shortcode patterns include [shiptrack_booking], [shiptrack-calendar], or similar. Verify the calendar form loads and accepts user input.
    Affected if The booking calendar form is rendered and functional on any public-facing page, allowing users to submit booking requests with input fields
  4. Identify exposed booking input parameters
    Inspect the HTML source of an active booking calendar page. Look for form fields that submit to the backend (typically POST requests to admin-ajax.php or the plugin's endpoint). Common field names include booking_date, customer_name, email, or similar booking-related parameters.
    Affected if Form fields are present and submit user-provided data directly to the plugin's backend processing without obvious sanitization indicators in the code

You are affected if the shiptrack Booking Calendar and Notification plugin is installed at version 4.0.3 or lower and the booking calendar form is accessible to users, as the unsanitized user input in this functionality enables the blind SQL injection.
