Summary
The HT Mega Addons for Elementor WordPress plugin before 3.2.6 does not restrict the HTML tag name used to render the section headline in several of its widgets and blocks to a safe allowlist, allowing users with contributor-level access and above to store a crafted tag name that executes arbitrary JavaScript when the content is viewed, including by higher-privileged users who review or publish it.
