What is CVE-2026-16947?

The Total Processing plugin for WooCommerce versions up to 7.3 has a significant security flaw that allows attackers to exploit improper path validation. This vulnerability enables unauthenticated users to craft malicious server-side requests, leading to the potential redirection of verification requests to unauthorized hosts. Consequently, this can expose sensitive payment-gateway credentials and enable attackers to forge success responses, falsely marking WooCommerce orders as paid. The implications are severe, making it essential for users to update and secure their installations promptly.

Affected Version(s)

Total processing card payments for WooCommerce 0 <= 7.3

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.
