CVE-2026-106101.

Disclosure summary

### Summary A DOM Clobbering vulnerability exists in Quasar's `openURL()` utility when handling the iOS `SafariViewController` bridge. The vulnerable implementation only checks whether `window.SafariViewController` exists before invoking it as a native bridge object. An attacker who can inject HTML content containing a named element such as `` can cause the browser to expose that element as `window.SafariViewController`. When `openURL()` is later called in an iOS environment, Quasar incorrectly treats the DOM element as the native bridge object and attempts to invoke bridge methods that do not exist, resulting in: ``` TypeError: window.SafariViewController.isAvailable is not a function ``` This can cause client-side denial of service and break navigation-related workflows in Quasar applications. ### Details Quasar provides the `openURL()` utility to open external URLs. On iOS platforms, this utility supports integration with the native `SafariViewController` bridge. The vulnerable code is located in: ``` ui/src/utils/open-url/open-url.js ```` The affected logic is: ```javascript if (Platform.is.ios && window.SafariViewController !== void 0) { window.SafariViewController.isAvailable
