Summary

Next.js is a React framework for building full-stack web applications.

For example: * [Not affected] `https://example.com/` * [Affected] `https://example.com/foo` * [Not affected] `https://example.com/foo/bar`. This issue is patched in Next.js `14.2.15` and later. If your Next.js application is hosted on Vercel, this vulnerability has been automatically mitigated, regardless of Next.js version. There are no official workarounds for this vulnerability.
