CVE-2026-58043 1 Nodejs 1 Node.js 2026-08-25 N/A 8.4 HIGH
A flaw in Node.js Permission Model enforcement can over-grant filesystem access across radix-tree prefix boundaries. Under `--permission`, an attacker who is granted access to one path can abuse boundary handling to read from or write to paths outside the intended filesystem allowlist. This vulnerability affects Node.js **main**, **22.x**, **24.x**, and **26.x**.
CVE-2026-56850 1 Nodejs 1 Node.js 2026-08-25 N/A 4.4 MEDIUM
A flaw in Node.js HTTPS Agent connection reuse can cause PFX object-array key collisions, allowing mutual TLS (mTLS) client identities to be reused across requests configured with different client certificates. This vulnerability affects Node.js **26.x**, **24.x**, and **22.x**.
CVE-2026-56847 1 Nodejs 1 Node.js 2026-08-25 N/A 6.1 MEDIUM
A flaw in Node.js Permission Model enforcement allows `trace_events.createTracing().enable()` Writes Trace Logs Outside `--allow-fs-write`. This can lead to confidentiality impact or bypass of the intended security boundary under affected configurations. This vulnerability affects Node.js **22.x**, **24.x**, and **26.x**.
CVE-2026-48617 1 Nodejs 1 Node.js 2026-08-19 N/A 8.2 HIGH
A flaw in Node.js Permission Model enforcement allows Bypass via `process.report.writeReport()` Path Misvalidation. This can lead to confidentiality impact or bypass of the intended security boundary under affected configurations. This vulnerability affects all supported release lines: **Node.js 22**, **Node.js 24**, and **Node.js 26**.
CVE-2026-21710 2 Nodejs, Redhat 3 Node.js, Enterprise Linux, Enterprise Linux Eus 2026-08-19 N/A 7.5 HIGH
A flaw in Node.js HTTP request handling causes an uncaught `TypeError` when a request is received with a header named `__proto__` and the application accesses `req.headersDistinct`. When this occurs, `dest["__proto__"]` resolves to `Object.prototype` rather than `undefined`, causing `.push()` to be called on a non-array. 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`. * This vulnerability affects all Node.js HTTP servers on **20.x, 22.x, 24.x, and v25.x**
CVE-2026-21712 1 Nodejs 1 Node.js 2026-08-19 N/A 6.5 MEDIUM
A flaw in Node.js URL processing causes an assertion failure in native code when `url.format()` is called with a malformed internationalized domain name (IDN) containing invalid characters, crashing the Node.js process.
CVE-2026-21711 1 Nodejs 1 Node.js 2026-08-19 N/A 5.3 MEDIUM
A flaw in Node.js Permission Model network enforcement leaves Unix Domain Socket (UDS) server operations without the required permission checks, while all comparable network paths correctly enforce them. As a result, code running under `--permission` without `--allow-net` can create and expose local IPC endpoints, allowing communication with other processes on the same host outside of the intended network restriction boundary. This vulnerability affects Node.js **25.x** processes using the Permission Model where `--allow-net` is intentionally omitted to restrict network access. Note that `--allow-net` is currently an experimental feature.
CVE-2026-21713 1 Nodejs 1 Node.js 2026-08-19 N/A 5.9 MEDIUM
A 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. Node.js already provides timing-safe comparison primitives used elsewhere in the codebase, indicating this is an oversight rather than an intentional design decision. This vulnerability affects **20.x, 22.x, 24.x, and 25.x**.
CVE-2026-21714 1 Nodejs 1 Node.js 2026-08-19 N/A 5.3 MEDIUM
A 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. This vulnerability affects HTTP2 users on Node.js 20, 22, 24 and 25.
CVE-2026-21715 1 Nodejs 1 Node.js 2026-08-19 N/A 3.3 LOW
A 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. As 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. This vulnerability affects **20.x, 22.x, 24.x, and 25.x** processes using the Permission Model where `--allow-fs-read` is intentionally restricted.
CVE-2026-21716 1 Nodejs 1 Node.js 2026-08-19 N/A 3.3 LOW
An 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. As 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. This vulnerability affects **20.x, 22.x, 24.x, and 25.x** processes using the Permission Model where `--allow-fs-write` is intentionally restricted.
CVE-2026-21717 1 Nodejs 1 Node.js 2026-08-19 N/A 5.9 MEDIUM
A flaw in V8'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's internal string table, an attacker can significantly degrade performance of the Node.js process. The 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. This vulnerability affects **20.x, 22.x, 24.x, and 25.x**.
CVE-2026-48937 1 Nodejs 1 Node.js 2026-08-18 N/A 7.5 HIGH
A flaw in Node.js HTTP/2 server API can cause servers to keep accepting data even after sending a `GOAWAY` frame. This vulnerability affects two supported release lines: **Node.js 22** and **Node.js 24**.
CVE-2023-44487 33 Akka, Amazon, Apache and 30 more 324 Http Server, Opensearch Data Prepper, Apisix and 321 more 2026-08-11 N/A 7.5 HIGH
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.
CVE-2026-48933 1 Nodejs 1 Node.js 2026-08-10 N/A 7.5 HIGH
A flaw in Node.js WebCrypto implementation can crash the process if the input of `subtle.encrypt()` is a multiple of 2GiB. This vulnerability affects all supported release lines: **Node.js 22**, **Node.js 24**, and **Node.js 26**.
CVE-2026-48618 1 Nodejs 1 Node.js 2026-08-10 N/A 6.5 MEDIUM
A flaw in Node.js TLS hostname handling can cause Node.js unicode dot separator handling can lead to tls wildcard-depth authentication bypass due to resolver and verifier hostname normalization mismat. This can lead to confidentiality impact or bypass of the intended security boundary under affected configurations. This vulnerability affects all supported release lines: **Node.js 22**, **Node.js 24**, and **Node.js 26**.
CVE-2025-59465 1 Nodejs 1 Node.js 2026-07-15 N/A 7.5 HIGH
A malformed `HTTP/2 HEADERS` frame with oversized, invalid `HPACK` data can cause Node.js to crash by triggering an unhandled `TLSSocket` error `ECONNRESET`. Instead of safely closing the connection, the process crashes, enabling a remote denial of service. This primarily affects applications that do not attach explicit error handlers to secure sockets, for example: ``` server.on('secureConnection', socket => { socket.on('error', err => { console.log(err) }) }) ```
CVE-2025-55130 1 Nodejs 1 Node.js 2026-07-15 N/A 9.1 CRITICAL
A flaw in Node.js’s Permissions model allows attackers to bypass `--allow-fs-read` and `--allow-fs-write` restrictions using crafted relative symlink paths. By chaining directories and symlinks, a script granted access only to the current directory can escape the allowed path and read sensitive files. This breaks the expected isolation guarantees and enables arbitrary file read/write, leading to potential system compromise. This vulnerability affects users of the permission model on Node.js v20, v22, v24, and v25.
CVE-2017-14919 1 Nodejs 1 Node.js 2026-07-14 5.0 MEDIUM 7.5 HIGH
Node.js before 4.8.5, 6.x before 6.11.5, and 8.x before 8.8.0 allows remote attackers to cause a denial of service (uncaught exception and crash) by leveraging a change in the zlib module 1.2.9 making 8 an invalid value for the windowBits parameter.
CVE-2016-9842 8 Apple, Canonical, Debian and 5 more 19 Iphone Os, Mac Os X, Tvos and 16 more 2026-07-14 6.8 MEDIUM 8.8 HIGH
The inflateMark function in inflate.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact via vectors involving left shifts of negative integers.
