WP STAGING Pro WordPress Backup Plugin | Before 5.1.3

How the Exploit Works

The WP STAGING and WP STAGING Pro WordPress Backup Plugins do not adequately protect information about ongoing backup processes. This allows an unauthenticated attacker to access the backup process information and subsequently download the backups. The attacker can then extract potentially sensitive data such as database content, configuration files, or proprietary code.

Conceptual Example Code

GET /wp-staging-backup-file HTTP/1.1
Host: vulnerable-wordpress-site.com

This simple HTTP GET request illustrates how an attacker might attempt to download a backup file from a vulnerable WordPress site. Note that the actual file location and request parameters would vary based on the specific site and backup configuration.
