    Title
    Post Duplicator < 3.0.15 - Contributor+ PHP Object Injection via customMetaData
    Summary
    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.
    Severity
    7.2 (High)
