Nuxt: Reflected XSS in `navigateTo()` external redirect
Nuxt is an open-source web development framework for Vue.js. From versions 3.4.3 to before 3.21.6 and 4.0.0-alpha.1 to before 4.4.6, navigateTo() with external: true generates a server-side HTML redirect body containing a tag. The destination URL is only sanitized by replacing " with %22, leaving <, >, &, and ' unencoded. An attacker who can influence the URL passed to navigateTo(url, { external: true }) can break out of the content="…" attribute and inject arbitrary HTML/JavaScript that executes under the application's origin. This issue has been patched in versions 3.21.6 and 4.4.6.
