Instead of plain strings, the type - * safe wrappers consume values of types from the goog.html package whose - * contract promises that values are safe to use in the corresponding context. - * - * Hence, a program that exclusively uses the wrappers in this file (i.e., whose - * only reference to security-sensitive raw DOM APIs are in this file) is - * guaranteed to be free of XSS due to incorrect use of such DOM APIs (modulo - * correctness of code that produces values of the respective goog.html types, - * and absent code that violates type safety). - * - * For example, assigning to an element's .innerHTML property a string that is - * derived (even partially) from untrusted input typically results in an XSS - * vulnerability. The type-safe wrapper goog.dom.safe.setInnerHtml consumes a - * value of type goog.html.SafeHtml, whose contract states that using its values - * in a HTML context will not result in XSS. Hence a program that is free of - * direct assignments to any element's innerHTML property (with the exception of - * the assignment to .innerHTML in this file) is guaranteed to be free of XSS - * due to assignment of untrusted strings to the innerHTML property. - */ - -goog.provide('goog.dom.safe'); -goog.provide('goog.dom.safe.InsertAdjacentHtmlPosition'); - -goog.require('goog.asserts'); -goog.require('goog.dom.asserts'); -goog.require('goog.html.SafeHtml'); -goog.require('goog.html.SafeScript'); -goog.require('goog.html.SafeStyle'); -goog.require('goog.html.SafeUrl'); -goog.require('goog.html.TrustedResourceUrl'); -goog.require('goog.string'); -goog.require('goog.string.Const'); - - -/** @enum {string} */ -goog.dom.safe.InsertAdjacentHtmlPosition = { - AFTERBEGIN: 'afterbegin', - AFTEREND: 'afterend', - BEFOREBEGIN: 'beforebegin', - BEFOREEND: 'beforeend' -}; - - -/** - * Inserts known-safe HTML into a Node, at the specified position. - * @param {!Node} node The node on which to call insertAdjacentHTML. - * @param {!goog.dom.safe.InsertAdjacentHtmlPosition} position Position where - * to insert the HTML. - * @param {!goog.html.SafeHtml} html The known-safe HTML to insert. - */ -goog.dom.safe.insertAdjacentHtml = function(node, position, html) { - node.insertAdjacentHTML(position, goog.html.SafeHtml.unwrap(html)); -}; - - -/** - * Tags not allowed in goog.dom.safe.setInnerHtml. - * @private @const {!Object} - */ -goog.dom.safe.SET_INNER_HTML_DISALLOWED_TAGS_ = { - 'MATH': true, - 'SCRIPT': true, - 'STYLE': true, - 'SVG': true, - 'TEMPLATE': true -}; - - -/** - * Assigns known-safe HTML to an element's innerHTML property. - * @param {!Element} elem The element whose innerHTML is to be assigned to. - * @param {!goog.html.SafeHtml} html The known-safe HTML to assign. - * @throws {Error} If called with one of these tags: math, script, style, svg, - * template. - */ -goog.dom.safe.setInnerHtml = function(elem, html) { - if (goog.asserts.ENABLE_ASSERTS) { - var tagName = elem.tagName.toUpperCase(); - if (goog.dom.safe.SET_INNER_HTML_DISALLOWED_TAGS_[tagName]) { - throw Error( - 'goog.dom.safe.setInnerHtml cannot be used to set content of ' + - elem.tagName + '.'); - } - } - elem.innerHTML = goog.html.SafeHtml.unwrap(html); -}; - - -/** - * Assigns known-safe HTML to an element's outerHTML property. - * @param {!Element} elem The element whose outerHTML is to be assigned to. - * @param {!goog.html.SafeHtml} html The known-safe HTML to assign. - */ -goog.dom.safe.setOuterHtml = function(elem, html) { - elem.outerHTML = goog.html.SafeHtml.unwrap(html); -}; - - -/** - * Sets the given element's style property to the contents of the provided - * SafeStyle object. - * @param {!Element} elem - * @param {!goog.html.SafeStyle} style - */ -goog.dom.safe.setStyle = function(elem, style) { - elem.style.cssText = goog.html.SafeStyle.unwrap(style); -}; - - -/** - * Writes known-safe HTML to a document. - * @param {!Document} doc The document to be written to. - * @param {!goog.html.SafeHtml} html The known-safe HTML to assign. - */ -goog.dom.safe.documentWrite = function(doc, html) { - doc.write(goog.html.SafeHtml.unwrap(html)); -}; - - -/** - * Safely assigns a URL to an anchor element's href property. - * - * If url is of type goog.html.SafeUrl, its value is unwrapped and assigned to - * anchor's href property.
