Object injection via unrestricted form deserialization

Published Sep 26, 2022 · Updated May 21, 2025

PHP object injection in Saturday Drive Ninja Forms before 3.6.13 allows remote authenticated users to instantiate objects via form imports. The favorite-fields import path passes uploaded serialized content to unserialize() without disabling class instantiation, invoking object wakeup methods. Administrator access and a suitable gadget chain on the WordPress site are required; consequences are limited by the available gadget methods.
