Authenticated PHP object injection via serialized form data
Published Mar 25, 2026 · Updated Mar 25, 2026
PHP object injection in WebToffee Product Feed for WooCommerce 2.3.3 and earlier allows remote authenticated users to inject PHP objects. Multiple AJAX handlers pass the POST form_data value through wp_unslash() to maybe_unserialize(), constructing attacker-supplied PHP objects. Shop Manager access is required, and file deletion, data retrieval, or code execution additionally requires a compatible POP chain from another installed plugin or theme.
