Vulnerability Overview
The Email Templates plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.4.2. This is due to missing or incorrect nonce validation on the send_test_email function. This makes it possible for unauthenticated attackers to send test emails via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Email Templates Customizer and Designer for WordPress and WooCommerce <= 1.4.2 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Email Templates Customizer and Designer for WordPress and WooCommerce the fix is 1.4.3: builds <= 1.4.2 are affected, anything from 1.4.3 onward is not.
Remediation
Update to version 1.4.3, or a newer patched version
