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 WP eCommerce WordPress plugin through 3.15.1 unserializes user input via ajax actions, which could allow unauthenticated users to perform PHP Object Injection when a suitable gadget is present on the blog.

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

The WP eCommerce WordPress plugin through version 3.15.1 has a PHP Object Injection vulnerability. The plugin unserializes user-supplied input via AJAX actions without proper validation, allowing unauthenticated attackers to inject malicious PHP objects if a suitable gadget chain exists in the WordPress environment.

MitigationUpdate the WP eCommerce plugin to the latest version beyond 3.15.1 when available. As a temporary measure, disable the plugin or restrict AJAX endpoints at the web server level until a patch is applied.

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. Verify WP eCommerce plugin is installed
    Locate the wp-content/plugins/wp-e-commerce folder, or check the Plugins page in WordPress admin, or query the database wp_options table for option_name = 'active_plugins'
    Affected if Plugin folder or database entry exists indicating the plugin is installed
  2. Check installed WP eCommerce version
    Open the main plugin file (wp-e-commerce.php) and look for the 'Version:' header comment, or check the Plugins page in WordPress admin, or query the wp_options table for option_name containing 'wp_e commerce_version'
    Affected if Version is 3.15.1 or lower (any version through 3.15.1)
  3. Confirm AJAX endpoint is accessible
    Test accessing the AJAX endpoint at /wp-admin/admin-ajax.php without authentication, or check if the wp-admin/admin-ajax.php file exists and responds to requests
    Affected if AJAX endpoint responds to requests (returns JSON response or triggers plugin AJAX handlers)
  4. Identify exposed AJAX actions
    Review plugin source code for do_action calls tied to AJAX hooks (wp_ajax_ and wp_ajax_nopriv_), or grep for 'add_action' with 'wp_ajax' in the plugin directory
    Affected if Plugin registers AJAX actions accessible to unauthenticated users (wp_ajax_nopriv_ hooks)

If WP eCommerce plugin version is 3.15.1 or lower and unauthenticated AJAX endpoints are accessible, the environment is affected by the PHP Object Injection vulnerability.
