CVE-2025-29927
Impact
It is possible to bypass authorization checks within a Next.js application, if the authorization check occurs in middleware.
Patches
15.2.314.2.25Note: Next.js deployments hosted on Vercel are automatically protected against this vulnerability.
Workaround
If patching to a safe version is infeasible, we recommend that you prevent external user requests which contain the
x-middleware-subrequestheader from reaching your Next.js application.Credits

Thank you to Allam Rachid (zhero) for the responsible disclosure. This research was rewarded as part of our bug bounty program.
CVE-2025-48068
Summary
A low-severity vulnerability in Next.js has been fixed in version 15.2.2. This issue may have allowed limited source code exposure when the dev server was running with the App Router enabled. The vulnerability only affects local development environments and requires the user to visit a malicious webpage while
npm run devis active.Because the mitigation is potentially a breaking change for some development setups, to opt-in to the fix, you must configure
allowedDevOriginsin your next config after upgrading to a patched version. Learn more.Learn more: https://vercel.com/changelog/cve-2025-48068

CVE-2025-55173
A vulnerability in Next.js Image Optimization has been fixed in v15.4.5 and v14.2.31. The issue allowed attacker-controlled external image sources to trigger file downloads with arbitrary content and filenames under specific configurations. This behavior could be abused for phishing or malicious file delivery.
All users relying on
images.domainsorimages.remotePatternsare encouraged to upgrade and verify that external image sources are strictly validated.More details at Vercel Changelog
CVE-2025-57752
A vulnerability in Next.js Image Optimization has been fixed in v15.4.5 and v14.2.31. When images returned from API routes vary based on request headers (such as
CookieorAuthorization), these responses could be incorrectly cached and served to unauthorized users due to a cache key confusion bug.All users are encouraged to upgrade if they use API routes to serve images that depend on request headers and have image optimization enabled.
More details at Vercel Changelog
CVE-2025-57822
A vulnerability in Next.js Middleware has been fixed in v14.2.32 and v15.4.7. The issue occurred when request headers were directly passed into
NextResponse.next(). In self-hosted applications, this could allow Server-Side Request Forgery (SSRF) if certain sensitive headers from the incoming request were reflected back into the response.All users implementing custom middleware logic in self-hosted environments are strongly encouraged to upgrade and verify correct usage of the
next()function.More details at Vercel Changelog
