DescriptionQuasar Framework is a framework for building high-performance Vue.js user interfaces. Prior to 2.32.2, the openURL() utility in ui/src/utils/open-url/open-url.js trusted window.SafariViewController whenever that global existed in an iOS environment. Attacker-controlled HTML rendered by components such as QEditor can create a named SafariViewController element, causing browser named-property resolution to replace the expected native bridge object. A later openURL() call then invokes isAvailable() on the element, throws a TypeError, and disrupts external navigation, login redirects, payment redirects, and other URL-opening workflows. QSelect and QChatMessage HTML-rendering configurations can expose the same trigger when they render attacker-controlled HTML. This issue is fixed in version 2.32.2.
