# TiendaCrypto WooCommerce plugin: forged payment webhooks mark orders as paid

The TiendaCrypto para WooCommerce WordPress plugin through 1.2.1 checks its payment webhook signature against an empty key, so the check always passes. An unauthenticated attacker can send forged webhook notifications and mark any WooCommerce order as paid.

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

## How to check

- Check the installed version of the TiendaCrypto para WooCommerce plugin in the WordPress admin under Plugins; versions through `1.2.1` are affected.
- Look for unpaid or pending WooCommerce orders marked as paid without a matching payment record at the crypto provider.

## Fix

- Update the TiendaCrypto para WooCommerce plugin to a version later than `1.2.1`; the sources do not name a fixed version.
- If no fixed version exists, disable the plugin until the webhook signature is verified against a real key.

## Timeline

## From the sources

The TiendaCrypto para WooCommerce WordPress plugin through 1.2.1 does not correctly verify the authenticity of its payment webhook, validating the request signature against a key that is always empty, which allows unauthenticated attackers to forge webhook notifications and mark arbitrary WooCommerce orders as paid on web servers that preserve request header case.
