CVE-2026-28074Network attack vector

Unauthenticated object injection via unsafe deserialization

Published Mar 5, 2026 · Updated Mar 5, 2026

PHP object injection in ThemeREX Pizza House 1.4.0 and earlier allows remote attackers to inject objects through untrusted serialized input. Public advisories do not identify the affected function, request parameter, or endpoint that deserializes the input. No authentication is required, but harmful effects beyond object creation depend on a suitable POP chain supplied by another installed plugin or theme; such a chain can expose data, delete files, or execute code.
