Advisory
Source description from Wordfence Intelligence, credited to Guillermo Álvarez Fernández.
The TeraWallet - Wallet for WooCommerce plugin for WordPress is vulnerable to unauthorized access in versions up to, and including, 1.6.9. This is due to use of order subtotal instead of the post-discount line item total when calculating the wallet credit amount for top-up purchases. This makes it possible for authenticated attackers, with subscriber-level access and above, to inflate their wallet balance beyond the amount paid by applying store coupons to wallet top-up purchases, as the credited amount was based on the pre-discount subtotal rather than the actual amount collected.
