SCA: security update for @nestjs/platform-fastify (GHSA-wf42-42fg-fg84)

high Tenable Self-Hosted Container Security Plugin ID 438906

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-33011)

Solution

Update the @nestjs/platform-fastify library and its related packages to version 11.1.16 or later.
