   @SR-G, no, your use case is actually pretty common: feeding Log4j to ELK. Actually, we even have a layout to ease this process: `JsonTemplateLayout`. In a nutshell, it was only `PatternLayout` that was performing interpolation on the formatted message, hence the rest of the layouts (incl. `JsonTemplateLayout`) are not affected by *this* vulnerability. Though right now there are 3 CVEs and depending on the use of lookups of your proprietary appender+layout, you might be affected.
