The DW Question & Answer plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.5.8. This is due to missing or incorrect nonce validation on the update_answer() function. This makes it possible for unauthenticated attackers to update answers to questions via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The DW Promobar WordPress plugin through 1.0.4 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks when the unfiltered_html capability is disallowed (for example in multisite setup)

The DW Question & Answer Pro WordPress plugin through 1.3.4 does not properly check for CSRF in some of its functions, allowing attackers to make logged in users perform unwanted actions, such as update a comment or a question status.

The DW Question & Answer Pro WordPress plugin through 1.3.4 does not check that the comment to edit belongs to the user making the request, allowing any user to edit other comments.
