Heroic WordPress theme: Cross-Site Request Forgery (CSRF)

Summary

The Heroic WordPress theme by webriti is vulnerable to Cross-Site Request Forgery in all versions up to and including 1.4.2. An attacker can create a malicious web page that makes a logged-in user unknowingly submit requests to the WordPress site, such as changing settings or adding content, depending on the victim's permissions. Exploitation requires that a logged-in user, typically an administrator or editor, visits the attacker's page. No fixed version is known, and Patchstack notes that the theme has not been updated for about 10 months.
