Access violation vulnerability in Backup Bolt 1.4.1

The Backup Bolt plugin for WordPress has a security issue that allows for unauthorized downloading of files and writing to backup locations. This affects all versions up to and including 1.4.1 through the use of the process_backup_batch() function. This vulnerability can be exploited by attackers with Administrator-level access or higher, allowing them to download files from outside the website’s main folder and save backup files to any location.
