  • Hi Chris we have used this plugin in our application. In light of the recent discovery of vulnerabilities with log4j2, we would like to know if this plugin uses the affected version Log4j2, and if yes, would you release an updated version of this plugin to counter the exploit of vulnerability?

  • in reply to vishnud126275

    Hello,

    The latest version does not use or import log4j at all. An older version did, but it did not include the library with the plugin and used the libraries available within the platform. So to ensure that you are covered you should ensure that the latest hotfix for your Appian platform has been applied, and that the latest version of the plugin is installed.

    Thanks,

    Chris
