SCA: security update for @fastify/busboy (GHSA-x8mw-p69m-v3mx)

high Tenable Self-Hosted Container Security Plugin ID 472069

Description

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

 - @fastify/busboy is a multipart form-data parser. In versions 1.0.0 through 3.2.0, an attacker who can
 submit multipart form-data can crash the parser by sending a part header whose name is a prototype-
 inherited property such as __proto__ or constructor. The internal header parser stores headers in a plain
 JavaScript object and assumes each value is an array, so an inherited property name resolves to a truthy
 non-array value and triggers a TypeError. In the common pipe integration the failure surfaces as an error
 event, but in direct write or end usage the exception is thrown synchronously and can terminate the
 Node.js process, causing an unauthenticated denial of service. The issue is fixed in @fastify/busboy
 3.2.1, which creates the header object with a null prototype. Users should upgrade to 3.2.1.
 (CVE-2026-19481)

Solution

Update the @fastify/busboy library and its related packages to version 3.2.1 or later.
