CVE-2023-6972

The Backup Migration plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.3.9 vi

The Backup Migration plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.3.9 via the 'content-backups' and 'content-name', 'content-manifest', or 'content-bmitmp' and 'content-identy' HTTP headers. This makes it possible for unauthenticated attackers to delete arbitrary files, including the wp-config.php file, which can make site takeover and remote code execution possible.
