This exception is thrown synchronously inside a property getter and cannot be intercepted by `error` event listeners, meaning it cannot be handled without wrapping every `req.headersDistinct` access in a `try/catch`.\n\n* This vulnerability affects all Node.js HTTP servers on **20.x, 22.x, 24.x, and v25.x**(CVE-2026-21710)\n\nA flaw in Node.js HMAC verification uses a non-constant-time comparison when validating user-provided signatures, potentially leaking timing information proportional to the number of matching bytes. Under certain threat models where high-resolution timing measurements are possible, this behavior could be exploited as a timing oracle to infer HMAC values.\n\nNode.js already provides timing-safe comparison primitives used elsewhere in the codebase, indicating this is an oversight rather than an intentional design decision.\n\nThis vulnerability affects **20.x, 22.x, 24.x, and 25.x**.(CVE-2026-21713)\n\nA memory leak occurs in Node.js HTTP/2 servers when a client sends WINDOW_UPDATE frames on stream 0 (connection-level) that cause the flow control window to exceed the maximum value of 2³¹-1. The server correctly sends a GOAWAY frame, but the Http2Session object is never cleaned up.\n\nThis vulnerability affects HTTP2 users on Node.js 20, 22, 24 and 25.(CVE-2026-21714)\n\nA flaw in Node.js Permission Model filesystem enforcement leaves `fs.realpathSync.native()` without the required read permission checks, while all comparable filesystem functions correctly enforce them.\n\nAs a result, code running under `--permission` with restricted `--allow-fs-read` can still use `fs.realpathSync.native()` to check file existence, resolve symlink targets, and enumerate filesystem paths outside of permitted directories.\n\nThis vulnerability affects **20.x, 22.x, 24.x, and 25.x** processes using the Permission Model where `--allow-fs-read` is intentionally restricted.(CVE-2026-21715)\n\nAn incomplete fix for CVE-2024-36137 leaves `FileHandle.chmod()` and `FileHandle.chown()` in the promises API without the required permission checks, while their callback-based equivalents (`fs.fchmod()`, `fs.fchown()`) were correctly patched.\n\nAs a result, code running under `--permission` with restricted `--allow-fs-write` can still use promise-based `FileHandle` methods to modify file permissions and ownership on already-open file descriptors, bypassing the intended write restrictions.\n\nThis vulnerability affects **20.x, 22.x, 24.x, and 25.x** processes using the Permission Model where `--allow-fs-write` is intentionally restricted.(CVE-2026-21716)\n\nA flaw in V8\u0026apos;s string hashing mechanism causes integer-like strings to be hashed to their numeric value, making hash collisions trivially predictable. By crafting a request that causes many such collisions in V8\u0026apos;s internal string table, an attacker can significantly degrade performance of the Node.js process.\n\nThe most common trigger is any endpoint that calls `JSON.parse()` on attacker-controlled input, as JSON parsing automatically internalizes short strings into the affected hash table.\n\nThis vulnerability affects **20.x, 22.x, 24.x, and 25.x**.(CVE-2026-21717)","status":"published","published":"2026-04-17T11:10:57Z","modified":"2026-08-18T01:19:39.205325962Z","cvss":[{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high"}],"updated_at":"2026-11-02T15:52:46.087701Z"},{"id":"RHSA-2026:6402","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update","status":"published","published":"2026-04-20T10:10:36Z","modified":"2026-10-16T10:22:16Z","cvss":[{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:21.91255Z"},{"id":"RHSA-2026:6431","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update","status":"published","published":"2026-04-20T10:10:39Z","modified":"2026-10-16T10:22:17Z","cvss":[{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:21.91255Z"},{"id":"RHSA-2026:7350","title":"Red Hat Security Advisory: nodejs:24 security update","status":"published","published":"2026-04-10T10:09:15Z","modified":"2026-10-20T10:15:16Z","cvss":[{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:22.928316Z"},{"id":"RHSA-2026:7386","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update","status":"published","published":"2026-04-21T10:09:53Z","modified":"2026-10-16T10:25:16Z","cvss":[{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:22.928316Z"},{"id":"RHSA-2026:7387","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update","status":"published","published":"2026-04-21T10:09:53Z","modified":"2026-10-16T10:25:18Z","cvss":[{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:22.928316Z"},{"id":"RHSA-2026:7670","title":"Red Hat Security Advisory: nodejs:24 security update","status":"published","published":"2026-04-13T10:07:20Z","modified":"2026-10-20T10:15:57Z","cvss":[{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:22.928316Z"},{"id":"RHSA-2026:7675","title":"Red Hat Security Advisory: nodejs24 security update","status":"published","published":"2026-04-13T10:07:23Z","modified":"2026-10-20T10:16:00Z","cvss":[{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:22.928316Z"},{"id":"RLSA-2026:7350","title":"Important: nodejs:24 security update","description":"Node.js is a software development platform for building fast and scalable network applications in the JavaScript programming language. \n\nSecurity Fix(es):\n\n* nodejs: Nodejs denial of service (CVE-2026-21637)\n\n* brace-expansion: brace-expansion: Denial of Service via unbounded brace range expansion (CVE-2026-25547)\n\n* minimatch: minimatch: Denial of Service via specially crafted glob patterns (CVE-2026-26996)\n\n* undici: Undici: Denial of Service due to uncontrolled resource consumption (CVE-2026-2581)\n\n* undici: Undici: HTTP header injection and request smuggling vulnerability (CVE-2026-1527)\n\n* undici: undici: Denial of Service via unbounded memory consumption during WebSocket permessage-deflate decompression (CVE-2026-1526)\n\n* undici: Undici: Denial of Service via invalid WebSocket permessage-deflate extension parameter (CVE-2026-2229)\n\n* undici: Undici: HTTP Request Smuggling and Denial of Service due to duplicate Content-Length headers (CVE-2026-1525)\n\n* undici: undici: Denial of Service via crafted WebSocket frame with large length (CVE-2026-1528)\n\n* nghttp2: nghttp2: Denial of Service via malformed HTTP/2 frames after session termination (CVE-2026-27135)\n\n* Node.js: Node.js: Denial of Service via malformed Internationalized Domain Name processing (CVE-2026-21712)\n\n* Node.js: Node.js: Denial of Service due to crafted HTTP `__proto__` header (CVE-2026-21710)\n\n* Node.js: Node.js: Information disclosure due to `fs.realpathSync.native()` bypassing filesystem read restrictions (CVE-2026-21715)\n\n* nodejs: Node.js: Permission bypass allows unauthorized modification of file permissions and ownership via incomplete security fix.
