Descriptions

The ActivityPub WordPress plugin before 1.0.0 does not ensure that post titles to be displayed are public and belong to the plugin, allowing any authenticated user, such as subscriber to retrieve the title of arbitrary post (such as draft and private) via an IDOR vector

El complemento ActivityPub de WordPress anterior a 1.0.0 no garantiza que los títulos de las publicaciones que se mostrarán sean públicos y pertenezcan al complemento, lo que permite a cualquier usuario autenticado, como un suscriptor, recuperar el título de una publicación arbitraria (como borrador y privada) a través de un IDOR vector

The ActivityPub plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 0.17.0 due to missing validation on a user controlled key. This can allow authenticated attackers, with subscriber-level permissions and above, to expose potentially sensitive post titles (e.g., draft and private post titles).
