Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Node.js HTTP 代理在连接复用方面存在一个缺陷，可能导致客户端将客户端在发出请求之前就已发送的响应误判为有效响应。此漏洞是 CVE-2026-48931 的不完整修复。 原本用于在接收到意外数据时销毁空闲保持活动（keep-alive）套接字的防护机制，仅会在事件循环轮询 I/O 时触发。如果某个未经请求的响应已到达套接字但尚未被读取，而此时该套接字已被分配给新的请求（例如，因为事件循环正忙于同步工作），那么防护机制将在未检测到该数据的情况下被移除，导致该数据被解析为新请求的响应。 此漏洞影响 Node.

Vulnerability Description
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**.
