  "summary": "CVE-2026-48932 is fixed in 4 products on 2 platforms, first by Node.js 26.3.1, released June 17, 2026. It is not reported as exploited. Patch Radar priority: Routine.",
  "title": "Node.js and 2 others: HTTP Request Smuggling",
  "description": "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 \u0060IncomingMessage\u0060 headers while piping the original body to a reused backend connection.\r\n\r\nNode.js can omit headers beyond \u0060maxHeadersCount\u0060 / \u0060maxHeaderPairs\u0060 from \u0060req.headers\u0060, \u0060req.rawHeaders\u0060, and \u0060req.headersDistinct\u0060, while still using those omitted headers internally for HTTP message framing. In particular, \u0060Content-Length\u0060 can be hidden from userland while the request body is still delivered.\r\n\r\nThis vulnerability affects all supported release lines: **Node.js 22**, **Node.js 24**, and **Node.js 26**.",
