AI-suggested

Upgrade the Duplicate Post plugin to version 1.5.8 or later, where this authorization flaw is fixed. No other mitigation is required if the plugin is updated.

Description

The Duplicate Post WordPress plugin versions before 1.5.8 contain an authorization flaw where users with roles granted access to the plugin, such as Contributor, can duplicate posts without verifying edit permissions. When the slug takeover option is enabled, this allows such users to move any readable post off its original permalink and publish their copy at that address.
