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.
