   Thanks for pointing that out.
   A Log4j 1.x bug (https://bugzilla.redhat.com/show_bug.cgi?id=2031667) does
   also exist albeit that it is not the same as the Zero Day vulnerability
   (10/10) and requires explicit configuration to enable the JMSAppender. If
   you set TopicBindingName or TopicConnectionFactoryBindingName to something
   that JNDI can handle … 1.x is vulnerable, just attack vector is "safer" as
   it depends on configuration.
   
   There are other RCE exploits against 1.x.  It’s end of life and a release
   of master branch with the upgrade to 2.15+ would be a good idea.
   
   I’m happy to perform the release unless you want to go ahead with it. Thanks
