CyberRota Analysis
AI-GeneratedThe multipart form-data parser for Fastify is vulnerable in versions 3.0.0 to 10.1.0, allowing unauthenticated clients to exploit the request.saveRequestFiles() function, which can lead to persistent disk consumption due to incomplete cleanup of temporary files when clients disconnect. This vulnerability poses a denial-of-service risk as it can result in linear growth of disk usage. Organizations using affected versions should prioritize upgrading to 10.1.1 to mitigate this risk.

Original NVD Description
@fastify/multipart is a multipart form-data parser for Fastify. In versions from 3.0.0 up to but not including 10.1.1, request.saveRequestFiles() can leave completed temporary files on disk when a client disconnects while the parser is advancing between multipart parts. The iterator rejection that occurs between parts falls outside the per-file cleanup path, so an earlier completed file is never removed. An unauthenticated client can repeat this to cause persistent, linear disk consumption, leading to denial of service. This is an incomplete-fix variant of CVE-2025-24033. The issue is fixed in @fastify/multipart 10.1.1. Users should upgrade to 10.1.1.
