Vulnerability Overview

The Form Block plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.0.1. This is due to missing or incorrect nonce validation on the get_requests() function. This makes it possible for unauthenticated attackers to submit forms on behalf of another user via a forged request granted they can trick a user into performing an action such as clicking on a link.

Technical Analysis

REMEDIATION: Update to version 1.0.2, or a newer patched version --- IDENTIFIER: CWE-352 (Cross-Site Request Forgery (CSRF)) The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
