CVE-2026-9834Public exploitNetwork attack vector

Administrator-level command execution via unescaped table exclusions

Published Jul 2, 2026 · Updated Jul 2, 2026

OS command injection in Magazine3 WP Database Backup 7.11 and earlier allows remote authenticated users to execute server commands. The mysqldump() function in includes/admin/class-wpdb-admin.php stores wp_db_exclude_table input, concatenates it into a shell command without escapeshellarg(), and later sends the resulting string to shell_exec() during a backup. Administrator-level WordPress access is required; injected commands run with the web server process privileges when a manual or scheduled backup executes.
