CVE-2021-4408

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.
