Advanced Custom Fields < 6.8.11 - Contributor+ Unpublished Post Title and Status Disclosure via Relational Fields

The Advanced Custom Fields (ACF®) WordPress plugin before 6.8.11 does not perform a read-permission check when it renders and formats the values of its relational fields, allowing users with post-editing access (Contributor and above) to disclose the titles and non-public statuses of other users' unpublished posts.
