Name of the Vulnerable Software and Affected Versions Post Duplicator versions prior to 3.0.15
Description Users with Contributor-level access and above can perform a PHP Object Injection. This occurs because the plugin fails to safely handle custom meta-data during post duplication, storing attacker-supplied serialized values without the double-serialization protection provided by the WordPress meta API. The issue involves the customMetaData variable.
Recommendations Update Post Duplicator to version 3.0.15 or later.
