The Wallet System for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'change_wallet_fund_request_status_callback' function in all versions up to, and including, 2.7.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to manipulate wallet withdrawal requests and arbitrarily increase their wallet balance or decrease other users' balances.
