CVE-2026-106102: Quasar Framework lets attackers inject malicious code
CVE-2026-106102 · published 4 days ago
Summary
The server‑side rendering feature in Quasar Framework versions before 2.22.0 does not properly encode data placed in page titles, meta tags, links or scripts. If an attacker can control that data—such as a post title or product name—they could insert harmful HTML that runs in users' browsers. Upgrade to Quasar Framework 2.22.0 or later to apply the fix.
What to do
- Update quasar to version 2.22.0.

Original advisory text
Quasar Framework: Stored/Reflected XSS via unescaped SSR meta tag rendering in getHead()
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.
