In the wake of the compromise of the eMudhra Intermediate CA, we strongly encourage all Mastodon administrators to make sure their systems are up-to-date.
For those using our official Mastodon container images, we just rebuilt them (with the same tags) so they contain the latest updates to the list of CA certificates. Please update them as soon as possible.
For more information about this compromise and ways to check if your server is impacted, please read https://emudhra.we-have-a-problem.com
