What is CVE-2026-93509?

The Wallet System for WooCommerce plugin suffers from an improper input validation flaw that allows authenticated attackers with Subscriber-level access to manipulate wallet transfer amounts. An attacker can exploit this vulnerability by minting wallet funds, as the system fails to ensure that transfer amounts are positive. Additionally, the plugin computes the sender's balance from an outdated snapshot before crediting the recipient, enabling attackers to drain funds from victims seamlessly.

Affected Version(s)

Wallet System for WooCommerce 2.0.0 < 2.8.0

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
