## Overview

YesWiki before 4.6.7 contains a cross-site request forgery vulnerability in RevisionsHandler that allows attackers to restore old page revisions through GET requests lacking CSRF token validation. Attackers can lure write-capable users into a top-level navigation with the restoreRevisionId parameter, silently overwriting current page content with stale or vandalized revisions.

## Remediation
