# WordPress Valitor payment plugin accepts forged payment confirmations

Link for people: https://infrastack.ai/live/CVE-2026-103361 (this .md is for agents)

The Payment Gateway via Valitor for WooCommerce plugin before 1.9.41 checks payment callbacks against a verification secret that ships with a hard-coded default. An unauthenticated attacker can forge a payment confirmation and mark any order as paid.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed plugin version in the WordPress admin under Plugins, or in the plugin's main file header.
- Check whether the verification secret in the plugin settings is still the default value.

## Fix

- Payment Gateway via Valitor for WooCommerce: move to `1.9.41` or later. Fixed version from the description; the sources give no further detail.

## Timeline

- 2026-11-15T07:36:11+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-103361

## From the sources

The Payment Gateway via Valitor for WooCommerce WordPress plugin before 1.9.41 does not properly validate the authenticity of payment callbacks, relying on a verification secret that ships with a hard-coded default value used by every store that has not changed it, allowing unauthenticated attackers to forge a valid payment confirmation and mark arbitrary orders as paid.
