The ActivityPub WordPress plugin before 1.0.0 does not ensure that post contents to be displayed are public and belong to the plugin, allowing any authenticated user, such as subscriber to retrieve the content of arbitrary post (such as draft and private) via an IDOR vector. Password protected posts are not affected by this issue.
