Recently a critical vulnerability (CVE-2021-44228) was discovered in the Apache Log4j library. This vulnerability can be exploited remotely without authentication and allows remote code execution. It ranks a 10 out of 10 on the CVSS severity level. It has pretty much set the world aflame. You can get more about what happened here and an overview with more links here.
More vulnerabilities are being discovered (CVE-2021-4104, CVE-2021-45046), information on them can be found below.
Yes. CVE-2021-44228 affects several of our products.
Update 2021-12-14: Another vulnerability related to Log4j has popped up: CVE-2021-4104. None of our products are vulnerable to this new CVE.
Update 2021-12-15: A third vulnerability, CVE-2021-45046, has been discovered. Some of our products are vulnerable. This CVE is only classed as a 3.7 out of 10, and can only be used to perform a DOS (denial-of-service) attack.
Update 2021-12-17: The above CVE-2021-45046 now had its severity level increased to 9, and also allows remote code execution. Still, Metabase says they are not using non default configurations, which makes it not vulnerable.
After the first vulnerability was published, we immediately started checking all our products for exposure to it. As was to be feared, many of our products use Log4j (or include third-party components that do), are therefore vulnerable, and need to be updated.

1) The fix releases in this column address CVE-2021-44228 both in our own code, and in Metabase.
2) The fix releases in this column address CVE-2021-45046 and are split in some cases. There are separate rows for cases where the older fix solves the issue in our code, but a newer fix with an updated Metabase version is needed to fix it there. See also 3).
3) To mitigate any remaining risk until we release a version with the updated Metabase release, see info box "Regarding Metabase" below.
Metabase includes Log4j and is vulnerable to CVE-2021-44228. For a first fix we update to Metabase 0.40.7 (which includes Log4j 2.15.0 and protects from the remote code execution exploit). Releases with this fix can be found in the left part of the table above. (column marked with 1) ) The more recently discovered CVE-2021-45046 requires Log4j 2.16.0 for which Metabase only recently released updates. If you are uncomfortable with the unofficial Metabase developer statement regarding CVE-2021-45046, you can go with the release that fixes the problem in our code and manually turn off Metabase for now:
