CVSS: 9.4EPSS: 84%CPEs: 3EXPL: 60CVE-2025-29927 – Authorization Bypass in Next.js Middleware
https://notcve.org/view.php?id=CVE-2025-29927
21 Mar 2025 — Next.js is a React framework for building full-stack web applications. Prior to 14.2.25 and 15.2.3, it is possible to bypass authorization checks within a Next.js application, if the authorization check occurs in middleware. If patching to a safe version is infeasible, it is recommend that you prevent external user requests which contain the x-middleware-subrequest header from reaching your Next.js application. This vulnerability is fixed in 14.2.25 and 15.2.3. • https://packetstorm.news/files/id/189975 • CWE-285: Improper Authorization •

17 Dec 2024 — Next.js is a React framework for building full-stack web applications. In affected versions if a Next.js application is performing authorization in middleware based on pathname, it was possible for this authorization to be bypassed for pages directly under the application's root directory. 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.

14 Oct 2024 — Next.js is a React Framework for the Web. Cersions on the 10.x, 11.x, 12.x, 13.x, and 14.x branches before version 14.2.7 contain a vulnerability in the image optimization feature which allows for a potential Denial of Service (DoS) condition which could lead to excessive CPU consumption. Neither the `next.config.js` file that is configured with `images.unoptimized` set to `true` or `images.loader` set to a non-default value nor the Next.js application that is hosted on Vercel are affected. This issue was f... • https://github.com/vercel/next.js/commit/d11cbc9ff0b1aaefabcba9afe1e562e0b1fde65a • CWE-674: Uncontrolled Recursion •

https://notcve.org/view.php?id=CVE-2023-46298
22 Oct 2023 — Next.js before 13.4.20-canary.13 lacks a cache-control header and thus empty prefetch responses may sometimes be cached by a CDN, causing a denial of service to all users requesting the same URL via that CDN. Next.js anterior a 13.4.20-canary.13 carece de un encabezado de control de caché y, por lo tanto, a veces una CDN puede almacenar en caché respuestas de captación previa vacías, lo que provoca una denegación de servicio a todos los usuarios que solicitan la misma URL a través de esa CDN. • https://github.com/vercel/next.js/compare/v13.4.20-canary.12...v13.4.20-canary.13 •

17 Feb 2022 — Next.js is a React framework. Starting with version 10.0.0 and prior to version 12.1.0, Next.js is vulnerable to User Interface (UI) Misrepresentation of Critical Information. In order to be affected, the `next.config.js` file must have an `images.domains` array assigned and the image host assigned in `images.domains` must allow user-provided SVG. If the `next.config.js` file has `images.loader` assigned to something other than default, the instance is not affected. Version 12.1.0 contains a patch for this ... • https://github.com/vercel/next.js/pull/34075 • CWE-451: User Interface (UI) Misrepresentation of Critical Information •

28 Jan 2022 — Next.js is a React framework. Starting with version 12.0.0 and prior to version 12.0.9, vulnerable code could allow a bad actor to trigger a denial of service attack for anyone using i18n functionality. In order to be affected by this CVE, one must use next start or a custom server and the built-in i18n support. Deployments on Vercel, along with similar environments where invalid requests are filtered before reaching Next.js, are not affected.
