Node.js security vulnerabilities
Node.js is an open-source, cross-platform JavaScript runtime environment developed by the Node.js community. Security vulnerabilities exist in Node.js versions 20.x, 22.x, 24.x, and 25.x. These vulnerabilities stem from HTTP/2 servers processing WINDOWUPDATE frames that cause the traffic control...
CVE-2026-21714: Missing Release of Memory after Effective Lifetime
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-2026-21711: Improper Access Control
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-2026-21710: Allocation of Resources Without Limits or Throttling
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-2026-21717: Use of Weak Hash
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-2026-21715: Incorrect Permission Assignment for Critical Resource
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-2026-21713: Observable Timing Discrepancy
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-2026-33939
Handlebars provides the power necessary to let users build semantic templates. In versions 4.0.0 through 4.7.8, when a Handlebars template contains decorator syntax referencing an unregistered decorator e.g. n, the compiled template calls lookupPropertydecorators, "n", which returns undefined. Th...

Handlebars provides the power necessary to let users build semantic templates. In versions 4.0.0 through 4.7.8, the Handlebars CLI precompiler "bin/handlebars" / "lib/precompiler.js" concatenates user-controlled strings — template file names and several CLI options — directly into the JavaScript ...
