When a user logs in with an alias address, rcube_user::query() matched the address against identity records without qualifying the lookup by IMAP host, so a login could be resolved to a user account belonging to a different IMAP host. Upstream fixed this in the commit \u201cFix bug where an alias login wasn\u2019t qualified by IMAP host\u201d."
