Source record

Technical description

The Sentence To SEO (keywords, description and tags) plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0. This is due to missing or incorrect nonce validation on the create_admin_page() function. This makes it possible for unauthenticated attackers to inject malicious web scripts and update plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
