## Description

The Better Post & Filter Widgets for Elementor plugin for WordPress is vulnerable to Sensitive Information Exposure via the /bpfwe/v1/filter REST route in all versions up to, and including, 1.9.1. This is because the route only checks whether the visitor is logged in, not whether they can read the requested document, before it renders elements of unpublished Elementor templates and pages. This makes it possible for authenticated attackers, with subscriber-level access and above, to view the rendered content of elements in draft and private templates and pages, provided they know the element's ID.
