Admin-level PHP object injection via unsafe settings deserialization
Published Nov 28, 2022 · Updated Apr 25, 2025
PHP object injection in ThemeHigh Checkout Field Editor for WooCommerce before 1.8.0 allows attackers to trigger gadget code via settings imports. The Backup and Import Settings workflow base64-decodes imported settings and passes attacker-controlled serialized data to PHP unserialize(). Administrator privileges and a suitable PHP gadget are required; successful exploitation invokes that gadget's defined behavior.
