Vulnerability Overview

The WP Extra File Types WordPress plugin before 0.5.1 does not have CSRF check when saving its settings, nor sanitise and escape some of them, which could allow attackers to make a logged in admin change them and perform Cross-Site Scripting attacks

Technical Analysis

REMEDIATION: Update to version 0.5.1, 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.
