Live › vulnerability › CVE-2026-111110
Go to dashboardThe GetPaid plugin for WordPress does not sanitize the 'mmdwqzpoxadd' parameter, so an unauthenticated visitor can store a script that runs for anyone who opens the affected page. The stored payload also fires when an administrator views the invoice's Payment Form Details metabox, which can lead to admin session takeover.

The Payment forms, Buy now buttons, and Invoicing System | GetPaid plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'mmdwqzpoxadd' parameter in all versions up to, and including, 2.8.61 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The required nonce (getpaid_form_nonce) is publicly emitted to all visitors via wp_localize_script as WPInv.formNonce, meaning no authentication or prior nonce leak is needed; the stored payload fires when an administrator views the affected invoice's Payment Form Details metabox.
