CVE-2026-49075Network attack vector

Conditional code execution via unsafe CCT deserialization

Published Jun 17, 2026 · Updated Jun 17, 2026

PHP object injection in Crocoblock JetEngine 3.8.9.1 and earlier allows remote authenticated users to inject PHP objects. The Custom Content Types item reader unserializes unauthorized serialized strings rather than limiting conversion to array-backed fields. Contributor-level access is required, and file deletion, sensitive-data retrieval, or code execution additionally requires a usable POP chain from another installed plugin or theme.
