Wolf CMS versions up to 0.8.3.1 contain an authorization bypass vulnerability in the BackupRestoreController component. This flaw allows authenticated non-administrative users to gain access to sensitive backup functionalities. The issue arises from a PHP operator precedence flaw in the expression used for permission checks. By exploiting this vulnerability, attackers can potentially create, download, and restore backups without requiring administrative privileges, leading to unauthorized access to sensitive data.
