The WP-ViperGB plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.6.1. This is due to missing or incorrect nonce validation when saving plugin settings. This makes it possible for unauthenticated attackers to change the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The wp-vipergb plugin before 1.3.16 for WordPress has XSS via add_query_arg() and remove_query_arg(), a different issue than CVE-2014-9460.

Multiple cross-site request forgery (CSRF) vulnerabilities in the WP-ViperGB plugin before 1.3.11 for WordPress allow remote attackers to hijack the authentication of administrators for requests that (1) change plugin settings via unspecified vectors or conduct cross-site scripting (XSS) attacks via the (2) vgb_page or (3) vgb_items_per_pg parameter in the wp-vipergb page to wp-admin/options-general.php.
