NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs:22/npm package and not the nodejs:22/npm package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A flaw in Node.js HTTP client can cause a request desynchronization for Node.js-based forwarding proxies that rebuild outbound headers from the visible IncomingMessage headers while piping the original body to a reused backend connection.

Node.js can omit headers beyond maxHeadersCount / maxHeaderPairs from req.headers, req.rawHeaders, and req.headersDistinct, while still using those omitted headers internally for HTTP message framing. In particular, Content-Length can be hidden from userland while the request body is still delivered.

This vulnerability affects all supported release lines: Node.js 22, Node.js 24, and Node.js 26.
