## Affected

- Unknown Walletdoc Payment Gateway for WooCommerce: fixed in 1.8.5

## Description

The Walletdoc Payment Gateway for WooCommerce WordPress plugin before 1.8.5 does not properly sanitize and escape user input before using it in a SQL statement, and verifies its payment webhook with a signing secret that is empty by default, allowing unauthenticated attackers to perform SQL injection attacks and to mark arbitrary orders as paid.
