description

Elementor Website Builder versions through 4.3.5 are affected by a cross-site scripting flaw. An attacker may cause code to run in a user's browser if the user interacts with attacker-controlled content.

mitigation

Disable the affected plugin or restrict public access to sites using it until a vendor update is confirmed. Review and limit untrusted content that can be displayed to site visitors.
