Log4J day-zero exploit CVE-2021-44228

[PRDuque]

Since Hubspot uses Log4J (https://product.hubspot.com/blog/bid/6011/log4j-dynamic-appender-configuration), does anyone knows what mitigation measures have been taken to deal with day-zero exploit CVE-2021-44228 ?

HubSpot uses Cloudflare (https://www.cloudflare.com/case-studies/hubspot/), and Cloudflare has already initiated mitigation measures (https://info.cloudflare.com/index.php/email/emailWebview?mkt_tok=NzEzLVhTQy05MTgAAAGBRbAScyE5IiQgYSp...).

But has HubSpot initiated some mitigation measures  by themselfs ?

We've published a landing page that will hopefully be helpful:

Thanks @jonathanhaber , this is very useful.

Not sure if already discussed, but it would be tremendously helpful if such information could be pushed out to us admins proactively. It took me some googling to even find this thread.

Have you updated all projects to log4j latest version, and deployed it to production?
