description

Green Invoice Morning for WooCommerce installations using wc-gateway-greeninvoice through 2.4.1 are affected by an authorization-control flaw. An unauthenticated attacker may access functionality or actions that should be restricted when the affected plugin functionality is reachable.

mitigation

Disable wc-gateway-greeninvoice until the vendor publishes a fixed release. If it must remain enabled, limit access to the site and its plugin-facing functionality to trusted networks and users.
