## Overview

LogicalDOC Community Edition through 9.3 contains an HQL injection vulnerability in DocumentsDataServlet that allows authenticated users to manipulate queries via the unvalidated indexed parameter. Attackers with read access to any folder can inject boolean HQL expressions to bypass folder scope and read-permission checks, listing restricted document metadata and extracting database contents.
