CVE-2026-21636

CVE-2026-21636 describes a security flaw in Node.js’s Permissions model where Unix Domain Socket (UDS) connections can bypass network restrictions even when --allow-net is not enabled. Attacker-controlled inputs (e.g., URLs or socketPath) could reach arbitrary local sockets via net, tls, or undic...

CVE-2025-59464

CVE-2025-59464 describes a memory leak in Node.js OpenSSL integration during conversion of X.509 certificate fields to UTF-8, occurring when applications call socket.getPeerCertificate(true). Each certificate field leaks memory, enabling steady memory growth over TLS connections and potentially c...

CVE-2025-55131

A flaw in Node.js's buffer allocation logic can expose uninitialized memory when allocations are interrupted, when using the vm module with the timeout option. Under specific timing conditions, buffers allocated with Buffer.alloc and other TypedArray instances like Uint8Array may contain leftover...

CVE-2025-59466

We have identified a bug in Node.js error handling where "Maximum call stack size exceeded" errors become uncatchable when asynchooks.createHook is enabled. Instead of reaching process.on'uncaughtException', the process terminates, making the crash unrecoverable. Applications that rely on...

CVE-2026-21637

A flaw in Node.js TLS error handling allows remote attackers to crash or exhaust resources of a TLS server when pskCallback or ALPNCallback are in use. Synchronous exceptions thrown during these callbacks bypass standard TLS error handling paths tlsClientError and error, causing either immediate...

CVE-2026-21637

CVE-2026-21637 is a Node.js TLS handling issue where synchronous exceptions in PSK/ALPN callbacks can bypass tlsClientError/error paths, causing process termination or FD leaks and potential DoS. Connected advisories (ALAS2023-2026-1404, ALAS2023-2026-1402, ALAS2023-2026-1403, CBLMARINER) confirm...

CVE-2025-59466

Summary: CVE-2025-59466 describes an issue in Node.js error handling where uncatchable stack-overflow crashes occur when async_hooks.createHook() is enabled. The crash bypasses uncaughtException handling and can cause process termination under deep recursion, affecting applications using AsyncLoc...

CVE-2025-59464

A memory leak in Node.js’s OpenSSL integration occurs when converting X.509 certificate fields to UTF-8 without freeing the allocated buffer. When applications call socket.getPeerCertificatetrue, each certificate field leaks memory, allowing remote clients to trigger steady memory growth through...

CVE-2025-59465

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...

CVE-2025-59465

CVE-2025-59465 is observed affecting Node.js packages across multiple Amazon Linux and Fedora advisories. The issue concerns Node.js HTTP/2 server handling of malformed HEADERS frames with oversized HPACK data, leading to a crash via an unhandled TLSSocket error (ECONNRESET) and remote DoS. Affec...

CVE-2025-55132

A flaw in Node.js's permission model allows a file's access and modification timestamps to be changed via futimes even when the process has only read permissions. Unlike utimes, futimes does not apply the expected write-permission checks, which means file metadata can be modified in read-only...

CVE-2026-21637

A flaw in Node.js TLS error handling allows remote attackers to crash or exhaust resources of a TLS server when pskCallback or ALPNCallback are in use. Synchronous exceptions thrown during these callbacks bypass standard TLS error handling paths tlsClientError and error, causing either immediate...

CVE-2026-21636

A flaw in Node.js's permission model allows Unix Domain Socket UDS connections to bypass network restrictions when --permission is enabled. Even without --allow-net, attacker-controlled inputs such as URLs or socketPath options can connect to arbitrary local sockets via net, tls, or undici/fetch...

Instead of safely closing the connection, the process crashes, enabling a remote denial of service. This primarily affects applications that do not...

CVE-2025-55130

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...
