✅ Remediation

Before applying the update, back up your existing installation, including all applications, configuration files, databases and database settings, and so on. The References section of this erratum contains a download link (you must log in to download the update). Workaround: In order to avoid the possibility of information access, review application source code for '@RunAs' and 'run-as-principal' usage. Also, make sure the application is using or not Elytron Security. It's possible to investigate by checking if the commands from '$JBOSS_HOME/docs/examples/enable-elytron.cli' or similar were executed.
