Published Jun 15, 2026 · Updated Jun 15, 2026

Path traversal in Groundhogg 4.4 and earlier allows remote authenticated users to delete arbitrary server files through its WordPress interface. The deletion request accepts a user-controlled file path without adequately restricting it to an intended directory. Sales Representative-level access is required; deleting wp-config.php can disable the site and enable code execution.
