Modoboa before 2.8.0 contains an insecure direct object reference vulnerability that allows authenticated users to create auto-reply messages for arbitrary mailboxes by supplying another user's mbox value. Attackers can POST to /api/v2/armessages/ to inject attacker-controlled auto-reply subject and content into victims' settings or break their auto-reply management via MultipleObjectsReturned errors.
