yarn nuxt 3.21.10
on Node.js Yarn

5 hours ago

⚠️ This is a security release. We recommend upgrading as soon as possible with npx nuxt upgrade --dedupe.

It fixes server-side RCE and unauthorized component instantiation via server island props, a route rule authorization bypass, server component DoS, and dev server path disclosure. Refreshing your lockfile also pulls in @nuxt/devtools@3.3.1, which fixes a separate critical development-only RCE.

If you already upgraded for the earlier route rule advisory (CVE-2026-53721), you still need this release: one of the fixes addresses a regression introduced by that fix.

Full details: Nuxt Security Patch Releases and GitHub Security Advisories.
