CVE-2026-27978: CWE-352: Cross-Site Request Forgery (CSRF) in vercel next.jsCVE-2026-27978 0 CVE-2026-27978 is a Cross-Site Request Forgery (CSRF) vulnerability in Next.js versions 16.0.1 up to but not including 16.1.7. The issue arises because the framework treated 'origin: null' as a missing origin during Server Action CSRF validation, allowing requests from opaque contexts like sandboxed iframes to bypass origin checks. This flaw enables attackers to trick users into submitting unauthorized Server Actions that can change state with the victim's credentials. The vulnerability is fixed in version 16.1.
