What is CVE-2026-103361?

The Payment Gateway via Valitor for WooCommerce plugin prior to version 1.9.41 has a significant security flaw that compromises payment confirmation processes. It does not adequately validate the authenticity of payment callbacks, relying on a hard-coded verification secret that is common across installations. This oversight enables unauthorized users to manipulate payment confirmations, potentially allowing attackers to mark arbitrary orders as paid without proper validation.

Affected Version(s)

Payment Gateway via Valitor for WooCommerce 0 < 1.9.41

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.
