Administrator-level object injection via unsafe update deserialization
Published Mar 27, 2025 · Updated Apr 28, 2026
PHP object injection in Cozmoslabs TranslatePress 2.9.6 and earlier allows remote authenticated users to inject objects via an update request. The trp_update_database action passes the trp_updb_extra_params request parameter to PHP unserialize(), reconstructing attacker-controlled objects. Administrator-level access is required, and no usable POP chain exists in TranslatePress itself; effects depend on a gadget supplied by another plugin or theme.
