Note
Adobe recommends updating your ColdFusion JDK/JRE LTS version to the latest update release as a secure practice. The ColdFusion downloads page is regularly updated to include the latest Java installers for the JDK version your installation supports as per the matrices below.
For instructions on how to use an external JDK, view Change ColdFusion JVM.
Adobe also recommends applying the security configuration settings included in the ColdFusion Security documentation as well as review the respective Lockdown guides.
