A few people have asked privately so it's probably worth publicly reassuring:

Snikket (and the software it builds upon, including Prosody) is *not* affected by the recent log4j vulnerability (CVE-2021-44228), so whether you use a hosted or self-hosted instance, this is one less service to worry about! ✔️


Also worth noting about other software:

- Jitsi Meet does use log4j in some components. Though it appears it probably wasn't vulnerable, the team have published a new release and it is definitely sensible to upgrade!

- Openfire was vulnerable and they have published a new release to which everyone should upgrade: discourse.igniterealtime.org/t (a workaround is also detailed)

- Tigase is another notable server written in Java, but it does not use log4j, so is not affected.
