CVE-2026-106102
CriticalCVSS 10.0Summary
Quasar Framework before 2.22.0 has a vulnerability in the SSR-only getHead() serializer that fails to properly encode values supplied via useMeta(). An attacker who can influence dynamic page metadata can inject executable HTML markup before hydration. The client-side path is not affected because it uses DOM APIs that encode attributes.
Risk Assessment
The risk includes injection of malicious code into server responses, potentially leading to user session hijacking or distribution of malicious content.
Recommendation
Update Quasar Framework to version 2.22.0 or later, which includes the fix.

In Quasar Framework prior to 2.32.2, the openURL() utility 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.
- CVE-2026-73647Medium
Quasar Framework prior to 2.22.0 contains a vulnerability in the public extend() utility in ui/src/utils/extend/extend.js that recursively copied attacker-controlled object keys during extend(true, target, source) deep merges without rejecting an own __proto__ property. The merge could descend into the prototype object and write attacker-controlled properties to Object.prototype in the same JavaScript process. Applications that passed user-controlled or partially user-controlled objects to extend() could experience logic bypass, unsafe default-option injection, denial of service, or other application-specific impact when polluted properties were later consumed. This issue is fixed in version 2.22.0.
Original NVD description (English source)
Quasar Framework is a framework for building high-performance Vue.js user interfaces. Prior to 2.22.0, the SSR-only getHead() serializer in ui/src/plugins/meta/Meta.js used getAttr() to interpolate values supplied through useMeta() into title, meta, link, and script markup without HTML text or quoted-attribute encoding. injectServerMeta() appended that output to the raw server-rendered response. An attacker who can influence dynamic page metadata, such as a post title, product name, excerpt, or display name, can terminate the intended HTML context and inject executable markup before hydration. The client-side apply() path is not affected because it uses DOM APIs that encode attributes. This issue is fixed in version 2.22.0.
