Advisory

Source description from Wordfence Intelligence, credited to Dhakal Ananda.

The Comments – wpDiscuz plugin for WordPress is vulnerable to insecure direct object reference in versions up to, and including, 7.4.2. This is due to insufficient validation on the 'wmu_attachments' user-controlled key. This makes it possible for authenticated attackers with subscriber-level capabilities and above to inject attachments that do not belong to them into post comments.
