WordPress Plugin Vulnerabilities
Ultimate Post Kit < 4.0.16 – Unauthenticated Arbitrary Post Content Disclosure
Description
The plugin exposes multiple AJAX “load more” endpoints such as upk_alex_grid_loadmore_posts without ensuring that posts to be displayed are published authentication. This allows an unauthenticated attacker to query arbitrary posts and retrieve rendered HTML content of private and unpublished ones.
