## Overview

YesWiki before 4.6.7 contains a missing authorization vulnerability in the listpagestag and includepages actions of the tags tool, which enumerate pages without applying read-ACL filtering. Unauthenticated or unprivileged attackers can embed these actions with a chosen tag or page name to disclose the names and body-derived titles of ACL-restricted pages.
