AI-suggested

Upgrade the Duplicate Post WordPress plugin to version 1.5.8 or later, where this issue is fixed. If upgrading is not immediately possible, restrict the roles that have access to the Duplicate Post plugin to trusted users only. Monitor plugin settings for unauthorized changes.

Description

The Duplicate Post WordPress plugin versions before 1.5.8 lack a proper capability check when saving global settings. Instead, they rely solely on their own role-access list, which can be manipulated by users with any role granted access by an administrator, including low-privilege roles such as Subscriber. This flaw allows such users to overwrite global settings, including the role-access list itself.
