Wallet System for WooCommerce < 2.8.2 - Subscriber+ KYC Document Overwrite via IDOR

Description

The plugin does not restrict its KYC document submission handler to the current user's own account, taking the target user ID from a client-supplied request field with no ownership or capability check, allowing authenticated users with minimal privileges such as Subscriber or Customer to overwrite the KYC documents and verification status of any other user, including an administrator.
