CVE-2024-38759Network attack vector

Unauthenticated object injection via database deserialization

Published Jul 22, 2024 · Updated Apr 28, 2026

PHP object injection in WP Media Search & Replace 3.2.2 and earlier allows remote attackers to instantiate objects from database data. The recursive_unserialize_replace path processes serialized database values with PHP unserialize() without disabling class instantiation, allowing magic methods to run. Exploitation is unauthenticated but requires a usable POP gadget chain from another installed plugin or theme; none exists in Search & Replace itself.
