Dokan: AI Powered WooCommerce Multivendor Marketplace Solution – Build Your Own Amazon, eBay, Etsy <= 4.2.4 - Insecure Direct Object Reference to PayPal Account Takeover and Sensitive Information Disclosure

Vulnerability Description

The Dokan: AI Powered WooCommerce Multivendor Marketplace Solution – Build Your Own Amazon, eBay, Etsy plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 4.2.4 via the `/wp-json/dokan/v1/settings` REST API endpoint due to missing validation on a user-controlled key. This makes it possible for authenticated attackers, with customer-level permissions and above, to read or modify other vendors' store settings including sensitive payment information (PayPal email, bank account details, routing numbers, IBAN, SWIFT codes), phone numbers, and addresses, and change PayPal email addresses to attacker-controlled addresses, enabling financial theft when the marketplace processes payouts.
