Medium severity, CVSS 5.3. EPSS: 0.3% chance of exploitation in the next 30 days.

The Ultimate Post Kit Addons for Elementor WordPress plugin before 4.0.16 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 This allows an unauthenticated attacker to query arbitrary posts and retrieve rendered HTML content of private and unpublished ones.
