{"id":"BIT-node-2026-58044","details":"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.\r\n\r\nNode.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.\r\n\r\nThis vulnerability affects all supported release lines: **Node.js 22**, **Node.js 24**, and **Node.js 26**.","aliases":["BIT-node-min-2026-58044","CVE-2026-58044"],"modified":"2026-08-17T08:11:03.401653141Z","published":"2026-08-17T05:52:35.230Z","database_specific":{"cpes":["cpe:2.3:a:nodejs:node.js:*:*:*:*:*:*:*:*"],"severity":"Low"},"references":[{"type":"WEB","url":"https://nodejs.org/en/blog/vulnerability/july-2026-security-releases"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58044"}],"affected":[{"package":{"name":"node","ecosystem":"Bitnami","purl":"pkg:bitnami/node"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"22.23.2"},{"introduced":"23.0.0"},{"fixed":"24.18.1"},{"introduced":"25.0.0"},{"fixed":"26.5.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/node/BIT-node-2026-58044.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N"}]}],"schema_version":"1.9.0"}
