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...

CVE-2025-55130

The CVE-2025-55130 entry describes a path traversal bypass in Node.js permission model: crafted relative symlink paths can cause reads/writes outside the allowed directory when --allow-fs-read/--allow-fs-write checks pass, enabling read/write of sensitive files and potential system compromise. Af...

CVE-2025-55132

The Connected documents confirm CVE-2025-55132: Node.js’ fs.futimes() can bypass the Read-Only permission model, allowing modification of file timestamps even when a process has only read access. Affected products are Node.js releases in the 20/22/24/25 lineages. Impact is potential log tampering...

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-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...

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...

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...

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...

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...
