## Overview

Form.io is a combined Form and API platform for Serverless applications. Versions 3.5.6 and below and 4.0.0-rc.1 through 4.4.2 contain a flaw in path handling which could allow an attacker to access protected API endpoints by sending a crafted request path. An unauthenticated or unauthorized request could retrieve data from endpoints that should be protected. This issue is fixed in versions 3.5.7 and 4.4.3.
