SCA: security update for @fastify/busboy (GHSA-gxm5-99cw-xjw9)

medium Tenable Cloud Security Plugin ID 472974

Description

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

 - @fastify/busboy is a multipart form-data parser for Node.js. Its multipart part-header parser splits
 header lines only on the two-byte carriage-return line-feed sequence, so a lone carriage return or line
 feed embedded in a part header is not treated as a line break and is carried verbatim into the parsed
 Content-Disposition filename and field name handed to the application. An attacker who uploads a file
 whose filename or field name contains a bare carriage return or line feed can inject control characters
 into consumers that trust the parser to return clean values, enabling filesystem filename pollution, log
 forging, or header injection when the value is forwarded to a carriage-return-sensitive sink. All versions
 of @fastify/busboy up to and including 3.2.1 are affected. The issue is fixed in version 3.2.2, which
 rejects any header line that still contains a bare carriage return or line feed. Users should upgrade to
 3.2.2, and consumers such as @fastify/multipart should bump their @fastify/busboy dependency to pull in
 the fix. (CVE-2026-74866)

Solution

Update the @fastify/busboy library and its related packages to version 3.2.2 or later.
