Security is a Habit

Staying up-to-date with new releases is a good habit to keep your MODX-powered websites secure. The security issues addressed in this release are limited to users that have a valid login to access the MODX Manager. A couple of the issues allowed changes or access beyond limited Manager users’ permissions. As such we recommend you upgrade as soon as possible.

Special Notes on Upgrading to 2.8.3

Some of the security improvements in 2.8.3 will affect certain site configurations. Read about these changes and how to make any appropriate adjustments when upgrading to 2.8.3.

It Takes a Village…
