CVE-2016-20076: Path traversal vulnerability

WordPress Simple-Backup 2.7.11 contains multiple vulnerabilities that allow unauthenticated attackers to delete arbitrary files and download sensitive files by manipulating the delete_backup_file and download_backup_file parameters in tools.php. Attackers can exploit insufficient input validation using directory traversal techniques to access wp-config.php, database dumps, and other sensitive files, or delete critical files .htaccess to expose backup directories.
