Nuxt is an open-source web development framework for Vue.js. From 3.4.0 until 3.21.10 and 4.5.1, an attacker can inject a template key through /__nuxt_island/ props into a dynamic component when `vue.runtimeCompiler: true` is enabled, causing template execution in the Nitro process. This issue is fixed in 3.21.10 and 4.5.1.
