Description
SchedulePress before 5.3.5 contains a missing authorization vulnerability that allows authenticated Contributor-level users to change any post's status and publish date via the wpsp_el_editor_form AJAX action. Attackers can reuse the wpsp-el-editor nonce from the Elementor modal to unpublish or reschedule administrator posts, or publish other users' pending or draft posts.
