  "details" : [ "A flaw in Node.js WebCrypto implementation can crash the process if the input of `subtle.encrypt()` is a multiple of 2GiB.\nThis vulnerability affects all supported release lines: **Node.js 22**, **Node.js 24**, and **Node.js 26**.", "A flaw was found in the Node.js WebCrypto implementation. A remote attacker could exploit this vulnerability by providing an input to the `subtle.encrypt()` function that is a multiple of 2 gigabytes (GiB). This could lead to a denial of service (DoS) by crashing the Node.js process." ],
  "statement" : "This is an Important denial of service vulnerability in Node.js WebCrypto, as a remote attacker can crash the Node.js process by providing a specially crafted large input to the `subtle.encrypt()` function. This could lead to service unavailability in Red Hat environments where Node.js applications process untrusted data with WebCrypto.",
