This attack appears to be exploitable via network client. This vulnerability… | ||
| CVE-2026-56848 | Hig | 0.49 | 7.5 | 0.01 | Aug 4, 2026 | A flaw in Node.js HTTP/2 handling allows `nghttp2_session_mem_send()` to be called re-entrantly while `nghttp2_session_mem_recv()` is executing, resulting in a heap-use-after-free. This vulnerability affects Node.js **26.x**, **24.x**, and **22.x**. | ||
| CVE-2026-56846 | Hig | 0.49 | 7.5 | 0.01 | Aug 4, 2026 | A flaw in Node.js HTTP/2 handling can cause HTTP/2 retained header blocks evade maxSessionMemory and enable remote memory exhaustion. This vulnerability affects Node.js **24.x** and **22.x**. | ||

Instead of reaching `process.on('uncaughtException')`, the process terminates, making the crash unrecoverable.… | ||
| CVE-2025-59464 | Hig | 0.49 | 7.5 | 0.00 | Jan 20, 2026 | A memory leak in Node.js’s OpenSSL integration occurs when converting `X.509` certificate fields to UTF-8 without freeing the allocated buffer.

| CVE-2025-23166 | Hig | 0.49 | 7.5 | 0.01 | May 19, 2025 | The C++ method SignTraits::DeriveBits() may incorrectly call ThrowException() based on user-supplied inputs when executing in a background thread, crashing the Node.js process. Such cryptographic operations are commonly applied to untrusted inputs. Thus, this mechanism… | ||
| CVE-2023-30587 | Hig | 0.49 | 7.5 | 0.01 | Sep 7, 2024 | A vulnerability in Node.js version 20 allows for bypassing restrictions set by the --experimental-permission flag using the built-in inspector module (node:inspector). By exploiting the Worker class's ability to create an "internal worker" with the kIsInternal Symbol, attackers… | ||
| CVE-2023-30583 | Hig | 0.49 | 7.5 | 0.01 | Sep 7, 2024 | fs.openAsBlob() can bypass the experimental permission model when using the file system read restriction with the `--allow-fs-read` flag in Node.js 20. This flaw arises from a missing check in the `fs.openAsBlob()` API. Please note that at the time this CVE was issued, the… | ||
| CVE-2024-22019 | Hig | 0.49 | 7.5 | 0.03 | Feb 20, 2024 | A vulnerability in Node.js HTTP servers allows an attacker to send a specially crafted HTTP request with chunked encoding, leading to resource exhaustion and denial of service (DoS). The server reads an unbounded number of bytes from a single connection, exploiting the lack of… | ||
| CVE-2023-30590 | Hig | 0.49 | 7.5 | 0.01 | Nov 28, 2023 | The generateKeys() API function returned from crypto.createDiffieHellman() only generates missing (or outdated) keys, that is, it only generates a private key if none has been set yet, but the function is also needed to compute the corresponding public key after calling… | ||
| CVE-2023-30585 | Hig | 0.49 | 7.5 | 0.01 | Nov 28, 2023 | A vulnerability has been identified in the Node.js (.msi version) installation process, specifically affecting Windows users who install Node.js using the .msi installer. This vulnerability emerges during the repair operation, where the "msiexec.exe" process, running under the… | ||
| CVE-2023-30581 | Hig | 0.49 | 7.5 | 0.01 | Nov 23, 2023 | The use of __proto__ in process.mainModule.__proto__.require() can bypass the policy mechanism and require modules outside of the policy.json definition. This vulnerability affects all users using the experimental policy mechanism in all active release lines: v16, v18 and, v20. … | ||
| CVE-2023-39331 | Hig | 0.49 | 7.5 | 0.01 | Oct 18, 2023 | A previously disclosed vulnerability (CVE-2023-30584) was patched insufficiently in commit 205f1e6.
