Next.js Framework 14.1.1 < 15.5.21 / 16.x < 16.2.11 SSRF

The Next.js Framework on the remote host is affected by a server-side request forgery vulnerability: - When a Server Action forwards or redirects a request, an attacker can cause the server to send that outbound request to a malicious host Server-Side Request Forgery. This requires the attacker's...

Denial Of Service (DoS)

Next.js is vulnerable to Denial Of Service. The vulnerability is due to insufficient validation of remotely hosted images processed by the Image Optimization API, where malicious image content can trigger excessive CPU consumption, allowing attackers to degrade application availability...

Server-Side Request Forgery

Next.js is vulnerable to Server-Side Request Forgery SSRF. The vulnerability is due to improper validation of request-controlled hostnames in rewrites and redirects rules, where attacker-controlled input can redirect requests to arbitrary hosts, allowing SSRF through rewrites or open redirects...

Denial Of Service

Next.js is vulnerable to Denial Of Service. The vulnerability is due to improper handling of crafted requests targeting applications using the App Router with Server Actions, allowing attackers to trigger excessive CPU usage and block processing of further requests...

Sensitive Information Exposure

Next.js is vulnerable to Sensitive Information Exposure. The vulnerability is due to exposure of Server Action identifiers in publicly served client artifacts, allowing unauthenticated attackers to discover protected Server Action endpoints and bypass authentication through endpoint enumeration...

Server-Side Request Forgery

Next.js is vulnerable to Server-Side Request Forgery SSRF. The vulnerability is due to improper validation of Host-associated headers during Server Action forwards and redirects, allowing attackers to redirect outbound requests to malicious or internal hosts and potentially expose sensitive...

Cache Confusion

Next.js is vulnerable to Cache Confusion. The vulnerability is due to improper caching of server-side fetch responses, where cached response bodies may be reused across requests with different request bodies, allowing confidential data from one request to be exposed to unauthorized users...

Denial Of Service (DoS)

Next.js is vulnerable to Denial Of Service DoS. The vulnerability is due to improper handling of requests targeting App Router applications with Server Actions running on the Edge runtime, allowing attackers to trigger excessive memory consumption and degrade application availability...

Sensitive Information Exposure

Next.js is vulnerable to Sensitive Information Exposure. The vulnerability is due to improper caching of server-side fetch responses for non-UTF-8 request bodies, where different request bodies can share the same cache entry, allowing confidential response data to be exposed to unauthorized...
