Critical Security Update - Versions Older than 7.1.2

Our security team was recently informed of a security vulnerability in a third-party component suite that is used within DNN Products. It is critical that you follow the instructions provided in this email to ensure that your site isn’t compromised.

IMPORTANT NOTE: Officially, any version prior to 8.4 is no longer supported.  We are offering this patch because we realize that some users are unable to upgrade at this time.  Please be aware that there are numerous other security vulnerabilities still in older versions.  This patch doesn't not protect your site from any other issue that have been previously reported in older version.  Your best course of action to ensure your site is protected is to upgrade to Version 9.1 and apply the security patch.

This vulnerability affects all versions of Evoq and DNN Platform.

In order to protect your site, you will need to download and install the Security Patch. You will install this package just like any other module in your site. Please follow the instructions in our documentation center for how to install an extension.

Please do not wait to protect your site. It will only take a few minutes to install the patch.
