Nuxt 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.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of nuxt/nuxt published their own advisory on GitHub. Reviewed sources take precedence over it.
