Summary
The BulletProof Security WordPress plugin is vulnerable to sensitive information disclosure due to a file path disclosure in the publicly accessible ~/db_backup_log.txt file which grants attackers the full path of the site, in addition to the path of database backup files. This affects versions up to, and including, 5.1.
