UBUNTU-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-2026-21715

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-2026-21715

The CVE-2026-21715 issue affects Node.js in the 20.x, 22.x, 24.x and 25.x streams with the Permission Model. The root cause is that fs.realpathSync.native() bypasses required read-permission checks, allowing code running with --permission and restricted --allow-fs-read to reveal file existence, r...

CVE-2026-21711

CVE-2026-21711 is a Node.js vulnerability describing a permission-check bypass in the Unix Domain Socket (UDS) handling under the Permission Model. The flaw allows code running with --permission and without --allow-net to create and expose local IPC endpoints, enabling potential cross-process com...

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-2026-21710

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-2026-21713

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...
