What the vulnerability does
01Description
The Post Snippits plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0. This is due to missing nonce validation on the settings page handlers for saving, adding, and deleting snippets. This makes it possible for unauthenticated attackers to modify plugin settings and inject malicious scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
