Vulnerability Overview
The Comments Extra Fields For Post,Pages and CPT plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 5.0. This is due to missing or incorrect nonce validation on several ajax actions. This makes it possible for unauthenticated attackers to invoke those actions via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. As a result, they may modify comment form fields and update plugin settings.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Comments Extra Fields For Post,Pages and CPT <= 5.0 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Comments Extra Fields For Post,Pages and CPT the fix is 5.1: builds <= 5.0 are affected, anything from 5.1 onward is not.
Remediation
Update to version 5.1, or a newer patched version
