Advisory
Source description from Wordfence Intelligence, credited to Jonas Benjamin Friedli.
The Backup Bolt plugin for WordPress is vulnerable to arbitrary file downloads and backup location writes in all versions up to, and including, 1.4.1 via the process_backup_batch() function. This makes it possible for authenticated attackers, with Administrator-level access and above, to download directories outside of the webroot and write backup zip files to arbitrary locations.
