CVE-2026-21713
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...
CVE-2026-21716
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...
CVE-2026-21717
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...
CVE-2026-21711
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 IP...
CVE-2026-21715
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...
CVE-2026-21714
A memory leak occurs in Node.js HTTP/2 servers when a client sends WINDOWUPDATE 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 vulnerabili...

CVE-2026-21710
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...

CVE-2026-21712
CVE-2026-21712 affects the Node.js package nodejs24 for versions less than 24.14.1-1 . The issue is a flaw in Node.js URL processing that triggers an assertion failure in native code when url.format() is called with a malformed internationalized domain name (IDN) containing invalid characters, cr...
CVE-2026-21714: Missing Release of Memory after Effective Lifetime
