CVE-2026-106107

high

Description

Quasar Framework is a framework for building high-performance Vue.js user interfaces. Prior to 3.3.0, several @quasar/app-vite SSR and SSG rendering paths interpolated ssrContext.nonce directly into quoted HTML attributes. An application that derives or overrides this value with attacker-controlled data can allow a quote to terminate the nonce attribute and inject additional attributes or markup into generated HTML across development and production SSR or SSG output. Cryptographically generated base64 or base64url nonces are not affected because they lack HTML attribute delimiters. This issue is fixed in version 3.3.0.
