Description Wolfgang Frisch 2020-06-15 13:47:23 UTC

CVE-2020-14093

Mutt before 1.14.3 allows an IMAP fcc/postpone man-in-the-middle attack via a
PREAUTH response. STARTTLS is not allowed in the Authenticated state, so previously Mutt would implicitly mark the connection as authenticated and skip any
encryption checking/enabling. No credentials are exposed, but it does allow messages to be sent to an attacker, via postpone or fcc'ing for instance.

You're right. I checked the CVE and the other bug did not have one yet.
