AI-suggested
Red Hat has not provided specific mitigation steps beyond monitoring for updates. Users should follow Red Hat advisories for future patches. Since this is a code injection and DOM Clobbering issue, limiting user input that can influence the DOM or disabling the vulnerable plugin where feasible may reduce risk until a fix is released.
