CVE-2022-3334Public exploitNetwork attack vector

Gadget-chain execution via imported-file deserialization

Published Oct 31, 2022 · Updated May 6, 2025

PHP object injection in Easy WP SMTP before 1.5.0 allows remote authenticated users to invoke gadget chains through a settings import. The Additional Settings import handler reads the uploaded file and passes its raw contents to PHP unserialize(), allowing object instantiation before the expected settings structure is validated. Administrator access and a suitable gadget chain already present on the WordPress site are required; resulting actions depend on that chain.
