En bref
- CVE-2026-33011 est une vulnérabilité ÉLEVÉE (CVSS 7.5) touchant nest (nestjs), @nestjs/platform-fastify.
- Probabilité d'exploitation dans les 30 prochains jours (EPSS) : 0.35%, plus élevée que 28.8% des vulnérabilités.
- Correctif : mettre à jour vers 11.1.16 ou plus récent.
Description
Impact
In a NestJS application using @nestjs/platform-fastify, GET middleware can be bypassed because Fastify automatically redirects HEAD requests to the corresponding GET handlers (if they exist).
As a result:
- Middleware will be completely skipped.
- The HTTP response won't include a body (since the response is truncated when redirecting a HEAD request to a GET handler).
- The actual handler will still be executed.
Patches
Fixed in @nestjs/[email protected]
NVD description
Nest is a framework for building scalable Node.js server-side applications. In versions 11.1.15 and below, a NestJS application using @nestjs/platform-fastify GET middleware can be bypassed because Fastify automatically redirects HEAD requests to the corresponding GET handlers (if they exist). As a result: middleware will be completely skipped, the HTTP response won't include a body (since the response is truncated when redirecting a HEAD request to a GET handler), and the actual handler will still be executed. This issue is fixed in version 11.1.16.
