Advisory
Source description from Wordfence Intelligence, credited to Mallory Adams, dwxsupport.
The Quiz And Survey Master plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.7.8. This is due to missing or incorrect nonce validation in the php/qmn_options_questions_tab.php file. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page via forged request granted they can trick a site administrator into performing an action such as clicking on a link.
