CVE-2026-128076

Nuxt is an open-source web development framework for Vue.js. From 3.21.6 to before 4.0.0 and from 4.4.6 until 4.6.4, the /nuxtisland path hash uses ohash serialization that does not escape quotes in string values or delimiters in object keys, allowing different island-prop tuples to produce the same path. For prerendering, substituted content is written into the generated page only if the crawler reaches a colliding URL before rendering the page with the legitimate props. Separately, a CDN or reverse proxy that keys island responses by path alone can be primed with the colliding response. If the substituted prop reaches v-html, innerHTML, or another unsafe HTML sink, the response can execute script in the application origin; otherwise the impact is content substitution. Applications that do not use server components or NuxtIsland, islands without attacker-influenced string props, and responses not cached by path alone are unaffected. This issue is fixed in version 4.6.4.
