Find real vulnerabilities before they ship
The Bottom Bar plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to and including 0.1.7. This is due to missing nonce verification on the plugin's settings update forms handled in bottom-bar-admin.php. None of the three settings forms (main settings, sharing services, restore defaults) include a wp_nonce_field(), and the server-side processing code never calls check_admin_referer() or any equivalent nonce validation before processing POST data and calling update_option(). This makes it possible for unauthenticated attackers to trick a logged-in administrator into submitting a crafted request that updates plugin configuration options, such as changing the language, maximum post counts, or enabled sharing services.
