Poznámka:

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. 

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