Note:
Adobe recommends updating your ColdFusion JDK/JRE to the latest version of the LTS releases for 1.8 and JDK 11. Applying the ColdFusion update without a corresponding JDK update will NOT secure the server. See the relevant Tech Notes for more details.
JEE Application Servers:
Users having JEE ColdFusion deployments (such as Tomcat, JBoss EAP) can refer to the instructions in https://helpx.adobe.com/coldfusion/kb/coldfusion-2018-update-8.html#jee

Acknowledgements
ColdFusion JDK Requirement
COLDFUSION 2018 HF1 and above
For Application Servers
On JEE installations, set the following JVM flag, "-Djdk.serialFilter= !org.mozilla.**;!com.sun.syndication.**;!org.apache.commons.beanutils.**", 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.
COLDFUSION 2016 HF7 and above
This security update requires ColdFusion to be on JDK 8u121 or higher. Adobe recommends that you must manually update your ColdFusion JDK/JRE to the latest version. In case you do not update the JDK/JRE, simply applying the update would NOT secure the server.
For Application Servers
Additionally, on JEE installations, set the following JVM flag, "-Djdk.serialFilter= !org.mozilla.**;!com.sun.syndication.**;!org.apache.commons.beanutils.**", in the respective startup file depending on the type of Application Server being used.
For example:
On Apache Tomcat Application Server, edit JAVA_OPTS in the ‘Catalina.bat/sh’ file
On WebLogic Application Server, edit JAVA_OPTIONS in the ‘startWeblogic.cmd’ file
On a 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
