## Affected

- sagesony Easy Flashcards: through 0.1

## Description

The Easy Flashcards plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 0.1. This is due to missing or incorrect nonce validation on the 'ef_settings_submenu' page. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
