They might reveal the plaintext of encrypted emails, including encrypted emails sent in the past. #efail 1/4" Thread starts here: https://twitter.com/seecurity/status/995906576170053633?s=21 I have no particular insight into what it is other than presuming from thread that decryption can be tricked to do bad things. They recommend temporary disabling downthread: "There are currently no reliable fixes for the vulnerability. If you use PGP/GPG or S/MIME for very sensitive communication, you should disable it in your email client for now.
