DOM-based XSS in SKT Blocks 2.2 and earlier allows remote authenticated users to execute scripts in visitors' browsers via affected Gutenberg blocks. The upstream changelog identifies the Post Grid, Post Carousel, and Post Timeline blocks, but public sources do not disclose the DOM source, sink, or faulty input-handling operation. Exploitation requires Contributor access and a site visitor to render affected content, enabling script execution in the visitor's browser context.
