Description
The LifterLMS plugin for WordPress is vulnerable to Sensitive Information Exposure via the Select2 post search AJAX handler (select2_query_posts) in all versions up to, and including, 10.3.0. The handler allowed any non-public post type whose capabilities fall back to the generic 'edit_posts' capability, such as coupons, and it allowed the public certificate post types without checking their edit capability. This makes it possible for authenticated attackers, with Contributor-level access and above, to retrieve the titles of published coupons (the coupon codes) and certificates.
