On July 24th, 2026, we received a submission for an Unauthenticated Arbitrary File Upload vulnerability in Elementor Pro, a WordPress plugin with an estimated 6,000,000 active installations. This vulnerability makes it possible for unauthenticated attackers to upload arbitrary files, including executable PHP files, to a vulnerable site, which can lead to remote code execution and complete site takeover. Exploitation requires the site to have published a page containing an Elementor Pro Form widget with at least one File Upload field that is not marked as required.
