Integration for Epos Now and WooCommerce 4.6.0 - 4.11.1 - Unauthenticated Action Scheduler Queue Disclosure

The Integration for Epos Now and WooCommerce WordPress plugin before 4.11.2 does not perform an authorization check on one of its REST endpoints, allowing unauthenticated users to retrieve the site's scheduled background tasks and their arguments, which include order identifiers and, when WooCommerce's deferred emails feature is enabled, the plaintext passwords of newly registered customers.
