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
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in flycart UpsellWP checkout-upsell-and-order-bumps allows Blind SQL Injection.This issue affects UpsellWP: from n/a through <= 2.2.4.

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

A blind SQL injection vulnerability exists in the flycart UpsellWP plugin (checkout-upsell-and-order-bumps functionality) affecting versions up to and including 2.2.4. The vulnerability allows attackers to inject malicious SQL queries through unsanitized input parameters, potentially enabling data exfiltration from the database.

MitigationUpgrade to a patched version of UpsellWP once available, or apply input validation and parameterized queries (prepared statements) to all database interactions within the vulnerable checkout-upsell-and-order-bumps code paths.

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 UpsellWP plugin installation
    Identify the plugin directory on the web server, typically under wp-content/plugins/, looking for directories named 'checkout-upsell-and-order-bumps', 'upsellwp', or similar naming patterns associated with the flycart UpsellWP plugin.
    Affected if The plugin directory exists on the server and contains UpsellWP files.
  2. Determine the installed plugin version
    Open the main plugin file (usually the primary PHP file in the plugin root) or the readme.txt file within the plugin directory and locate the version declaration or header comment specifying the version number.
    Affected if The version number found is 2.2.4 or lower.
  3. Verify the checkout-upsell-and-order-bumps feature is active
    Check the WordPress admin plugin settings page for UpsellWP, or inspect the database wp_options table for records related to 'upsellwp' or 'checkout_upsell' configuration that indicate the feature is enabled.
    Affected if The checkout-upsell-and-order-bumps functionality is enabled in the plugin settings or actively used on the site.
  4. Identify SQL interaction points in the vulnerable code path
    Search plugin PHP files within the checkout-upsell-and-order-bumps directory for direct database query construction (such as $wpdb->prepare with unsanitized variables, direct $wpdb->query calls, or raw SQL concatenation) that handle user-supplied input from request parameters.
    Affected if Code exists that processes request parameters (GET, POST, or cookie values) directly into SQL queries without using prepared statements or input sanitization functions.

A user is affected if the UpsellWP plugin is installed with version 2.2.4 or lower, the checkout-upsell-and-order-bumps feature is active, and unsanitized user input flows into SQL query execution within that feature's code paths.
