Risks of Log4j 2 with the Prometheus Exporter?

Just a simple question here -- does the Prometheus Exporter present a risk
for the Log4j 2 vulnerability?  It was added to the news page but
instinctively I don't see how an attacker might exploit it.  If it's not
expected to be a concern, I think we should state so in the news; no reason
to raise undue alarm bells.  Maybe we should remove it.

Correct.  I just reviewed occurrences of log.info, log.warn etc. and it's
all boring stuff that definitely doesn't take user input.

I'm going to remove this from the news in my PR:
https://github.com/apache/solr-site/pull/54

Can someone explain why it’s no risk & can’t be exploited? Because it doesn’t take input?

I was wondering about this, too. It makes mitigation too complex. There is no risk in the exporter script. Just mention this as a single sentence.

Possibly also add the sentence u declining the importance and why in my previous message on private list.
