What is CVE-2025-14434?

The Ultimate Post Kit Addons for Elementor plugin versions prior to 4.0.16 suffer from an improper access control vulnerability. Specifically, multiple AJAX endpoints, such as upk_alex_grid_loadmore_posts, are exposed without proper authentication checks. This oversight allows unauthenticated attackers to access and query arbitrary posts, retrieving rendered HTML content of private and unpublished posts, significantly compromising the privacy of sensitive content.
