I'd be very surprised were that the case with stable. It hasn't
happened to me, and I think that you'd immediately see a lot of
complaints if it happened.

But your advice to check is good. We can't assume that the OP hasn't
changed the temporary directory location, as it can be changed outside
of mutt's configuration files:

 3.347. tmpdir

 Type: path
 Default: (empty)

 This variable allows you to specify where Mutt will place its temporary files
 needed for displaying and composing messages. If this variable is not set, the
 environment variable $TMPDIR is used. If $TMPDIR is not set then “/tmp” is
 used.

However, I've opened my local mailbox, deleted messages, and quit,
all without any file manipulations in /tmp/ (my $TMPDIR is unset).

Unpacking an archive can then change the permissions; eg from
man tar:

   Overwrite control
       These options control tar actions when extracting a file over an existing copy on disk.

       [ … ]

       --no-overwrite-dir
              Preserve metadata of existing directories.

       [ … ]

       --overwrite-dir
              Overwrite metadata of existing directories when extracting (default).

Disclaimer: As far as the OP is concerned, I notice that their system
has suffered unaccountable changes in permission settings before, eg:
https://lists.debian.org/debian-user/2014/07/msg00059.html

¹ eg https://lists.debian.org/debian-user/1997/11/msg01557.html
