CVE-2026-53722— Nuxt 跨站脚本漏洞

Nuxt: Reflected XSS in `<NuxtLink>` via unsanitised `javascript:` or `data:` URL

Nuxt is an open-source web development framework for Vue.js. Prior to versions 3.21.7 and 4.4.7, <NuxtLink> did not validate the URL scheme of values bound to its to or href props before rendering them into the href attribute of the underlying <a> element. When an application binds attacker-controlled input (a query parameter, a CMS field, a user-supplied profile URL) to <NuxtLink :to> or :href, the attacker can supply a javascript: or vbscript: URL that is reflected verbatim into the rendered markup. Clicking the link executes the supplied script in the origin of the Nuxt application, resulting in reflected DOM-based cross-site scripting. A data:text/html,... payload reflected through the same sink does not execute in the application's origin but enables a same-tab phishing surface anchored to a legitimate application link. The same value was exposed to consumers of the component's custom slot via the href and route.href props, so applications that re-bind those values to their own anchors were affected identically. This issue has been patched in versions 3.21.7 and 4.4.7.

Nuxt 跨站脚本漏洞

Nuxt是Nuxt团队开源的一个免费的开源框架。 Nuxt 3.21.7之前版本和4.4.7之前版本存在跨站脚本漏洞，该漏洞源于<NuxtLink>未验证绑定到to或href属性的URL方案，可能导致反射型DOM-based跨站脚本攻击。
