Elementor Website Builder for WordPress before version 3.4.8 does not sanitize or escape user-controlled input appended to the DOM from a malicious URL hash fragment. This permits DOM-based cross-site scripting.

This repository provides a containerized lab environment simulating a DOM-based Cross-Site Scripting (XSS) vulnerability in the Elementor Website Builder WordPress plugin (CVE-2021-24891). The structure includes a Dockerfile for setting up a WordPress 5.8 instance with the vulnerable plugin, and a full WordPress directory tree under 'app/'. The README.md gives detailed instructions for launching the lab using Docker or GitHub Codespaces, and explains the vulnerability: the Elementor editor's JavaScript reads the URL hash and injects it into the DOM without sanitization, allowing an attacker to craft a link with a malicious JavaScript payload in the hash fragment. When a logged-in admin visits such a link, the script executes in their browser context, potentially leading to session hijacking or site compromise. The main attack vector is browser-based, requiring social engineering to get an admin to click a crafted link. The repository is educational, not weaponized, and does not include automated exploitation scripts, but provides a realistic environment for manual exploitation and study of the vulnerability.
