Advisory
Source description from Wordfence Intelligence, credited to Stefan Löwen.
The Wallet System for WooCommerce plugin for WordPress is vulnerable to Improper Input Validation in versions 2.0.0 through 2.7.10. This is due to missing validation that the transfer amount is a positive number, combined with use of abs() on the sender's stale pre-credit balance when computing the debit, and trust of a client-supplied user ID. This makes it possible for authenticated attackers, with subscriber-level access and above, to mint wallet funds for themselves or drain another user's wallet balance by submitting a negative transfer amount, exploiting the absolute-value debit and a stale pre-credit balance snapshot.
