FetchMetadata Plugin

Features

This Joomla Plugin helps to protect your sites by using Fetch Metadata Request Headers

The implemened rules are:
- Step 1: Allow requests from browsers which don't send Fetch Metadata
- Step 2: Allow same-site and browser-initiated requests
- Step 3: Allow simple top-level navigation and iframing
- Step 4: Opt out endpoints that are meant to serve cross-site traffic (Optional)
- Step 5: Reject all other requests that are cross-site and not navigational
