The Action Network plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4.4. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The Action Network plugin for WordPress is vulnerable to SQL Injection via the 'bulk-action' parameter in version 1.4.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
