Description Martin Prpič 2016-08-02 09:39:02 EDT 
It was found that MongoDB creates a world-readable .dbshell history file in a user's directory:

The mongodb client doesn't store authentication commands, but there's still information leakage, though, even if only about database and collection names, or data structure.

As for data itself, the history could also contain sensitive information; for instance, if usernames for some other service were stored in a mongo collection, the history could contain lines like:

  db.users.find({user:"foo"})

or even:

  db.users.update({user:"foo"},{$set:{password:"OhComeOnNow"}})

Created mongodb tracking bugs for this issue:

Affects: fedora-all [bug 1362554]
Affects: epel-all [bug 1362555]
Comment 2 Marek Skalický 2016-08-02 10:18:37 EDT 
So should be Fedora and EPEL bugs fixed if this bug is closed as WONTFIX?

> So should be Fedora and EPEL bugs fixed if this bug is closed as WONTFIX?

I'll leave that decision to the Fedora/EPEL maintaner but seeing as this was closed upstream, and home directories in RHEL and Fedora are not world readable to other users, I don't see this as something worth developing an out-of-band patch for.
Comment 4 Pavel Raiskup 2016-09-27 02:15:25 EDT 
FWIW, this seems to be fixed upstream in the end, in link from comment #0.
Comment 5 Marek Skalický 2016-09-27 04:46:27 EDT 
Fedora/EPEL bugs are already fixed/in testing.
