ملاحظة:

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

CF2018: https://helpx.adobe.com/pdf/coldfusion2018-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.
