Read the original description
The Advanced Custom Fields (ACF®) WordPress plugin before 6.8.11 does not verify that a user is allowed to edit the target object before writing to it during bidirectional relationship synchronization, allowing users with contributor-level access and above to add or remove a reference to their own object on arbitrary posts, users, or terms they cannot otherwise edit.
