Note: Chrome 62 does not appear to mutate this particular string any more, instead it just leaves the "whitespace" in place. In another window, navigate to your project directory and then run the worker: cd flask-by-example python worker. The sanitizer contains a bit of code that triggers this mutation on an inert piece of DOM, before angular sanitizes it. First, fire up Redis in one terminal window: redis-server. Note that the style element is not closed and will be replaced with before adding it to the DOM, closing the style element early and reactivating img.Īffected versions of this package are vulnerable to Cross-site Scripting (XSS).īrowsers mutate attributes values such as   javascript:alert(1) when they are written to the DOM via innerHTML in various vendor specific ways. with DOMPurify), the transformation done by JQLite may modify some forms of an inert, sanitized payload into a payload containing JavaScript - and trigger an XSS when the payload is inserted into DOM. via new JQLite(aString)) with user-controlled HTML string that was sanitized (e.g. One of the modifications performed expands an XHTML self-closing tag. JQLite (DOM manipulation library that's part of AngularJS) manipulates input HTML before inserting it to the DOM in jqLiteBuildFragment. XSS may be triggered in AngularJS applications that sanitize user-controlled HTML snippets before passing them to JQLite methods like JQLite.prepend, JQLite.after, JQLite.append, JQLite.replaceWith, JQLite.append, new JQLite and angular.element. It also lets you use HTML as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly.Īffected versions of this package are vulnerable to Cross-site Scripting (XSS).

If you need to use a number of Angular tags, it’s a good idea to change the template tags AngularJS uses with the $interpolateProvider. Ready?
