ColdFusion (2021 release) Update 1

ColdFusion (2021 release) Update 1


On Windows, if ColdFusion is running as a service with a non-default custom service name, shut down ColdFusion, and then apply the Update using ColdFusion package manager on all applicable ColdFusion instances with the command:

cfpm.bat update all

What's new and changed

ColdFusion (2021 release) Update 1 (release date, 22 March, 2021) features the following:

  • Address vulnerabilities mentioned in the document APSB21-16.
  • Activation and deactivation of Virtual Core licenses. To accommodate virtual core licensing, few changes were done in the license validation workflow. This can result in signature validation errors when the server comes up after the update is applied. If the server is online, activation will be re-attempted and server will continue as usual if the activation is successful. If the server is offline, users will need to offline-activate the server once again as the server could have reverted to the Trial or Developer mode. This is a one-time activity and will not be needed to be done when future updates are released.
  • Introduced support for RHEL 8.3, WildFly 23, Tomcat 9.0.43, PostgreSQL 13, Oracle 19c (2018), and MS SQL Server 2019.
  • Bug fixes.

Note: After installing this update, you might encounter the message after updating all packages using the ColdFusion Package Manager. The message is purely cosmetic and does not impact the installation of the packages.

Known issues in this release

Bug ID




While installing the Hotfix, the following error message displays:

"Error occurred while installing PMT update. Please try again."



When trying to update/install packages in ColdFusion (2021 release), and your CF is a standalone one, and  you see this message,

"One or more packages require the server to be at update 1. Since the server is at update 0, you must install the update 1 of the server. After upgrading the server update, the packages can be installed."

Try the workaround below:

  1. Navigate to [CF Home]\cfusion\
  2. Add a key, installtype=standalone.
  3. Save the file, and restart your ColdFusion server as well as the cfpm utility.

Update workflow


If you are trying to update your ColdFusion server using the hotfix and the cfpm process becomes unresponsive (for more than 30 minutes), it may be an issue with the hotfix installation. As a workaround, kill the cfpm process and try restarting the ColdFusion process.

Update workflow


If installing or updating the package cfajax, restart the ColdFusion server for the changes to take effect.

Administrator UI


When applying Update 1 of ColdFusion (2021 release), do not enable the check-box to update the instances from cfusion itself. Apply the update to each instance.



On IE and Safari browsers, you are unable to copy and paste the license key.



Using variable name in brackets, [varName], in a CFC throws an invalid CFML exception.



  1. On 64-bit computers, use 64-bit JRE for 64-bit ColdFusion.
  2. If the ColdFusion server is behind a proxy, specify the proxy settings for the server to get the update notification and download the updates. Specify proxy settings using the system properties below in the jvm.config for a stand-alone installation, or corresponding script file for JEE installation.
    • http.proxyHost
    • http.proxyPort
    • http.proxyUser
    • http.proxyPassword
  3. For ColdFusion running on JEE application servers, stop all application server instances before installing the update.


ColdFusion Administrator

In Package Manager > Packages, click Check for Updates in Core Server.

After it detects an update, click Update. The core package gets updated the the latest update.

All installed packages also get updated.

Restart ColdFusion for the changes to take effect.

Install the update manually

  1. Click the link to download the JAR.
  2. Execute the following command on the downloaded JAR. You must have privileges to start or stop ColdFusion service and full access to the ColdFusion root directory.

    Windows: <cf_root>/jre/bin/java.exe -jar <jar-file-dir>/hotfix-001-325996.jar

    Linux-based platforms: <cf_root>/jre/bin/java -jar <jar-file-dir>/hotfix-001-325996.jar

Ensure that the JRE bundled with ColdFusion is used for executing the downloaded JAR. For standalone ColdFusion, this must be at, <cf_root>/jre/bin.

Install the update from a user account that has permissions to restart ColdFusion services and other configured webservers .

For further details on how to manually update the application, see the help article.

Post installation


After applying this update, the ColdFusion build number should be 2021,0,01,325996.


To uninstall the update, perform one of the following:

  • In ColdFusion Administrator, click Uninstall in Server Update Updates Installed Updates.
  • Run the uninstaller for the update from the command prompt. For example, java -jar {cf_install_home}/{instance_home}/hf_updates/hf-2021-00001-325996/uninstall /uninstaller.jar

If you can't uninstall the update using the above-mentioned uninstall options, the uninstaller could be corrupted. However, you can manually uninstall the update by doing the following:

  1. Delete the update jar from {cf_install_home}/{instance_name}/lib/updates.
  2. Copy all folders from {cf_install_home}/{instance_name}/hf-updates/{hf-2021-00001-325996}/backup directory to {cf_install_home}/{instance_name}/
