SCA: security update for @fastify/busboy (GHSA-xjh9-v7x6-24jw)

high Tenable Self-Hosted Container Security Plugin ID 472270

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 3.1.0 through 3.2.0, a remote unauthenticated
attacker can stall the Node.js event loop by sending a multipart request whose boundary is crafted to a
specific length. The vendored streaming search stores its skip table in a fixed 256 entry byte array, and
a boundary of exactly 252 bytes makes the search needle 256 bytes, which truncates the default skip
distance to zero and turns the search into a CPU bound loop on a small body. A single small request can
keep one core busy and deny service to other requests handled by the same process. The issue is fixed in
@fastify/busboy 3.2.1, which widens the skip table so the skip distance is preserved. Users should upgrade
to 3.2.1. (CVE-2026-19484)

Solution

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