CVE-2026-33011: Nestjs Nest

High severity, CVSS 7.5. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

• Nestjs Nest: before 11.1.16 (fixed in 11.1.16)
