GetPaid is a WordPress plugin that handles payment forms, buy-now buttons, and invoicing for online businesses. An unauthenticated attacker can inject malicious scripts into payment forms that execute when administrators view invoice details, potentially leading to account compromise or malware distribution. The vulnerability requires no authentication because the necessary security token is publicly visible to all website visitors.

Technical details

The plugin suffers from stored cross-site scripting (XSS) in the 'mmdwqzpoxadd' parameter due to insufficient input sanitization and output escaping. An unauthenticated attacker can inject arbitrary JavaScript that persists in the database and executes when an administrator accesses the Payment Form Details metabox; the attack is possible because the nonce (getpaid_form_nonce) is publicly exposed via wp_localize_script, eliminating the need for authentication or nonce leakage.
