Authentication/authorization bypass in Clerk's official JavaScript SDKs (@clerk/nextjs, @clerk/nuxt, @clerk/astro, and the underlying @clerk/shared) allows unauthenticated remote attackers to defeat middleware-based route protection: a crafted request evades createRouteMatcher so that clerkMiddleware never invokes auth.protect(), letting the request reach protected downstream handlers such as API routes and server components. Sessions are not compromised and no user is impersonated — only the middleware gating decision is bypassed — so real impact is confined to apps that rely solely on middleware gating without redundant checks in their handlers. CVSS is 9.1 and SSVC rates technical impact as total, but there is no public exploit identified at time of analysis and EPSS is low at 0.09% (26th percentile).
Next.js is a React framework for building full-stack web applications. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, no authentication required. This Server-Side Request Forgery (SSRF) vulnerability could allow attackers to make the server perform requests to unintended internal or external resources.
Next.js is a React framework for building full-stack web applications. Rated medium severity (CVSS 6.2), this vulnerability is no authentication required, low attack complexity.
Next.js is a React framework for building full-stack web applications. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity.
A remote code execution vulnerability (CVSS 9.1). Critical severity with potential for significant impact on affected systems.
A security vulnerability in Next.js applications. In Auth0 Next.js SDK (CVSS 7.7). High severity vulnerability requiring prompt remediation.
Next.js is a React framework for building full-stack web applications. Rated low severity (CVSS 2.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Next.js is a React framework for building full-stack web applications. Rated low severity (CVSS 3.7), this vulnerability is remotely exploitable, no authentication required. No vendor patch available.
Next.js is a React framework for building full-stack web applications. Rated low severity (CVSS 1.7), this vulnerability is remotely exploitable, no authentication required. No vendor patch available.
Next.js versions 1.11.4 through 15.2.2 contain a critical middleware authorization bypass via the x-middleware-subrequest header. Attackers can send crafted requests that skip middleware entirely, bypassing authentication, authorization, and security headers enforced at the middleware layer.
Next.js is a React framework for building full-stack web applications. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
ZEIT Next.js before 2.4.1 has directory traversal under the /_next and /static request namespace, allowing attackers to obtain sensitive information. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and EPSS exploitation probability 80.8%.
