Summary

Security updates

This release features several security fixes. Because this is a security release, it is recommended that you update your sites immediately.

The security team would like to thank the following people for responsibly reporting vulnerabilities, and allowing them to be fixed in this release:

A Blind SSRF issue reported by sibwtf, and subsequently by several other researchers while the fix was being worked on
A PoP-chain weakness in the HTML API and Block Registry reported by Phat RiO
A regex DoS weakness in numeric character references reported by Dennis Snell of the WordPress Security Team
A stored XSS in nav menus reported by Phill Savage
An AJAX query-attachments authorization bypass reported by Vitaly Simonovich
A stored XSS via the data-wp-bind directive reported by kaminuma
An XSS that allows overridding client-side templates in the admin area reported by Asaf Mozes
A PclZip path traversal issue reported independently by Francesco Carlucci and kaminuma
An XXE in the external getID3 library reported by Youssef Achtatal

The WordPress security team have worked with the maintainer of the external getID3 library, James Heinrich, to coordinate a fix to getID3. A new version of getID3 is available here.
As a courtesy, these fixes are being backported, where necessary, to all branches eligible to receive security fixes (currently through 4.7). As a reminder, only the most recent version of WordPress is actively supported.
