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 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.
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.
