## Description

The WP Popular Posts plugin for WordPress is vulnerable to Sensitive Information Exposure via the popular posts REST API endpoints and widgets in all versions up to, and including, 7.4.3. This is due to the Translate::get_object_id() function returning the translated post ID from the 'wpml_object_id' filter without checking whether that translation is published. This makes it possible for unauthenticated attackers to view the title, link and content of unpublished (draft, pending or private) translations of popular posts, for example by passing the 'lang' parameter to the /v1/popular-posts endpoint, on sites that use WPML or a compatible multilingual plugin.
