  "details": "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 \u003cmeta http-equiv=\"refresh\"\u003e tag. The destination URL is only sanitized by replacing \" with %22, leaving \u003c, \u003e, \u0026, 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.",
