Recommendation: Plan a near-term fix — a public PoC already exists.
The Post Duplicator WordPress plugin before 3.0.15 does not safely handle custom meta-data during post duplication, storing attacker-supplied serialized values without the WordPress meta API's double-serialization protection, allowing users with Contributor-level access and above to inject a PHP Object.
