Unsanitized HTML parsing methods
Newly Available (since 2025-09-15)
Expected to be Widely Available on 2028-03-15
The Document.parseHTMLUnsafe() static method parses HTML into a DOM tree, while the setHTMLUnsafe() method of Element and ShadowRoot parses and inserts HTML into an existing tree. No sanitization applies to these methods, so never call them with user-provided HTML strings.
