Release of Joomla! 3.4.7 Update your site!

26 November, 2021

Joomla! 3.4.7 is now available - it's an another security release of the Joomla 3.x series that address a critical security vulnerability.

This release only contains the reported security fixes and additional security hardening of the UploadShield sytem (MySQLi driver).
No other changes have been made compared to the Joomla 3.4.6 release.

Since the recent Joomla update it has become clear that the root cause is a bug in PHP itself. But the only sites affected by this bug are those hosted on vulnerable PHP versions. This release fixes the bug across all supported PHP versions.

It is very important to update the current version of Joomla immediately. Without the update your site is open to being hacked!

If you're using Joomla 3 - update it to version 3.4.7 immediately.
