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 missing authorization vulnerability in the Product Price by Formula for WooCommerce plugin (versions up to 2.5.6) allows unauthenticated or unauthorized users to access functionality they should not have access to, likely enabling manipulation of product price formulas without proper capability checks.

MitigationUpdate the plugin to the latest version when available. If no patch exists, implement proper WordPress capability checks (e.g., 'manage_options' or 'edit_products') on all AJAX endpoints and admin pages that handle price formula configuration.

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 the plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Product Price by Formula for WooCommerce'. Note the installed version displayed next to the plugin name.
    Affected if The plugin is installed and the version is below 2.5.7 or cannot be determined
  2. Identify the installed version number
    Locate the plugin version in the plugin header comment within the main plugin file (typically in /wp-content/plugins/product-price-by-formula-for-woocommerce/ or similar path). Compare this version to 2.5.7 as the patched reference.
    Affected if The installed version is lower than 2.5.7 or the version cannot be verified
  3. Inspect AJAX endpoints for missing capability checks
    Review the plugin PHP files for AJAX action handlers (add_action calls with wp_ajax_ or wp_ajax_nopriv_ prefixes). Check if these handlers include current_user_can() or similar capability verification before executing sensitive operations on pricing formulas.
    Affected if AJAX endpoints exist that process pricing formula data without verifying user capabilities (no current_user_can() check found)
  4. Review callback functions for authorization
    Examine the plugin PHP files for callback functions that handle product price modifications. Look for whether these functions first validate user permissions using current_user_can('manage_options') or 'edit_products' capability before allowing changes.
    Affected if Functions that modify pricing formulas do not perform capability checks at the function entry point

The environment is affected if the Product Price by Formula for WooCommerce plugin is installed with a version below 2.5.7 AND AJAX endpoints or functions lack proper capability validation before allowing access to pricing formula modifications.
