Summary

The TiendaCrypto para WooCommerce WordPress plugin from 1.0.1 through 1.2.1 does not correctly verify the signature of its payment webhook (CWE-347), because it checks the request signature against a key that is always empty. On web servers that preserve request header case, an unauthenticated attacker can forge webhook notifications and mark arbitrary WooCommerce orders as paid. A public exploit is linked in the references.

Description from the CNA

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.
