DescriptionNuxt is an open-source web development framework for Vue.js. From 4.4.0 until 4.5.1, runtime cache:nuxt:payload entries for /<page>/_payload.json can be returned before route middleware and page guards because import.meta.prerender is not enforced, disclosing another user's SSR data. This issue is fixed in 4.5.1.
