SCA: security update for @fastify/middie (GHSA-8p85-9qpw-fwgw)

high Tenable Self-Hosted Container Security Plugin ID 438139

Description

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

 - A vulnerability in @fastify/middie versions < 9.2.0 can result in authentication/authorization bypass when
 using path-scoped middleware (for example, app.use('/secret', auth)). When Fastify router normalization
 options are enabled (such as ignoreDuplicateSlashes, useSemicolonDelimiter, and related trailing-slash
 behavior), crafted request paths may bypass middleware checks while still being routed to protected
 handlers. (CVE-2026-2880)

Solution

Update the @fastify/middie library and its related packages to version 9.2.0 or later.
