Summary

Node.js 26.x, 24.x and 22.x HTTP Agent connection reuse is affected. An unsolicited response that reaches an idle keep-alive socket before a new request is handed to it is parsed as the response to that request, due to a race condition (CWE-367). An attacker who can send such a response to a client's connection can exploit this, with high attack complexity and no privileges needed. It is an incomplete fix of CVE-2026-48931.

Description from the CNA

A flaw in Node.js HTTP Agent connection reuse can cause a client to accept as valid a response that was sent before the client has sent the request. This is an incomplete fix of CVE-2026-48931. The guard that destroys idle keep-alive sockets when unexpected data arrives only runs when the event loop polls for I/O. If an unsolicited response has already reached the socket but has not been read yet when the socket is handed to a new request, for example because the event loop was busy with synchronous work, the guard is removed without seeing it and the data is parsed as the response to the new request. This vulnerability affects Node.js **26.x**, **24.x**, and **22.x**.
