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

Missing authorization vulnerability in the Payment Plugins for PayPal WooCommerce plugin (pymntpl-paypal-woocommerce) allows unauthenticated attackers to access certain functions or endpoints that should require proper access control validation. This enables exploitation of incorrectly configured security levels in the plugin's access control implementation.

MitigationImplement proper authorization checks on all sensitive endpoints and functions, ensuring that user permissions are validated before executing any privileged operations. Update to the latest plugin version once available.

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. Check installed plugin version
    Locate the plugin in wp-content/plugins/pymntpl-paypal-woocommerce/ and open the main PHP file to read the Version header, or check the plugin row in WordPress admin under Plugins > Installed Plugins
    Affected if Version is 2.0.13 or lower (all versions up to and including 2.0.13 lack proper authorization checks)
  2. Verify plugin is active
    In WordPress admin, go to Plugins > Installed Plugins and confirm the Payment Plugins for PayPal WooCommerce plugin shows as Active
    Affected if Plugin is active and version is 2.0.13 or lower, making the missing authorization flaw exploitable
  3. Audit plugin endpoints for access control
    Review plugin source code in includes/ and src/ directories for AJAX handlers, REST API routes, or admin pages that perform sensitive actions without calling current_user_can() or wp_get_current_user() authorization checks
    Affected if Any sensitive functionality found without proper user authorization validation before executing
  4. Check for unauthenticated API access
    Examine server access logs and test plugin endpoints with a logged-out browser session to see if the plugin accepts requests without authentication
    Affected if Plugin processes requests from unauthenticated users without rejecting them

A user is affected if the Payment Plugins for PayPal WooCommerce plugin is active at version 2.0.13 or lower and exposes sensitive functionality without verifying user authorization.
