[GitHub] [logging-log4j2] SR-G edited a comment on pull request #607: LOG4J2-3198: Log4j2 no longer formats lookups in messages by default

   Does anyone know "when" exactly inside the LOG4J2 stack this bug may be triggered ? Is it only at "rendering" level, or may it be before ?
   
   For the context, in my case : all logs are routed by LOG4J2 (2.14.0), but trapped by a specific appender in which LoggingEvent are transformed into something else, and these transformed objects are then stored into an ElasticSearch database. After that, the display of these logs is done in a proprietary way (without LOG4J2 being involved in any way). So my feeling is that in this very specific situation, this security issue could not be triggered ... assuming the problematic code is only triggered inside LOG4J2 layout rendering. Hence this question, any ideas about "when" this problem can be triggered ?
