CVE-2026-106107

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.

Several @quasar/app-vite SSR and SSG renderer paths interpolate ssrContext.nonce directly into quoted HTML attributes. An application that derives or overrides the nonce using untrusted data can allow a quote to terminate the nonce attribute and inject additional attributes or markup into generated HTML.

Cryptographically generated base64 or base64url nonces are not directly affected because they do not contain HTML attribute delimiters. Exploitation requires an application to place attacker-controlled or otherwise unsafe data in ssrContext.nonce.

The remediation centralizes nonce handling across development SSR/SSG, production SSR, production SSG, critical CSS, store-state scripts, and Vue Devtools. It validates the value as a non-empty base64/base64url CSP nonce and HTML-encodes the attribute value before rendering.
