Note:

Adobe recommends updating your ColdFusion JDK/JRE LTS version to the latest update release. Check the ColdFusion support matrix below for your supported JDK version.

ColdFusion Support Matrix:

CF2023: https://helpx.adobe.com/pdf/coldfusion2023-suport-matrix.pdf

CF2021: https://helpx.adobe.com/pdf/coldfusion2021-support-matrix.pdf

Applying the ColdFusion update without a corresponding JDK update will NOT secure the server.  See the relevant Tech Notes for more details.

Adobe  also recommends customers apply the security configuration settings as outlined on the ColdFusion Security page as well as review the respective Lockdown guides.    

ColdFusion JDK Requirement

COLDFUSION 2023 (version 2023.0.0.330468) and above
For Application Servers

On JEE installations, set the following JVM flag, “-Djdk.serialFilter= !org.mozilla.**;!com.sun.syndication.**;!org.apache.commons.beanutils.**;!org.jgroups.**;!com.sun.rowset.**" in the respective startup file depending on the type of Application Server being used.

For example:
Apache Tomcat Application Server: edit JAVA_OPTS in the ‘Catalina.bat/sh’ file
WebLogic Application Server: edit JAVA_OPTIONS in the ‘startWeblogic.cmd’ file
WildFly/EAP Application Server: edit JAVA_OPTS in the ‘standalone.conf’ file
Set the JVM flags on a JEE installation of ColdFusion, not on a standalone installation.
