  "details" : [ "Svelte devalue is a JavaScript library that serializes values into strings when JSON.stringify isn't sufficient for the job. From version 5.6.3 to before version 5.8.1, devalue.parse could, due to quirks in some JavaScript engines, be convinced to allocate much more memory than was needed when deserializing sparse arrays, leading to excessive memory consumption. This issue has been patched in version 5.8.1.", "A flaw was found in devalue, a JavaScript library used for serializing values. Due to quirks in some JavaScript engines, the `devalue.parse` function could be exploited by a remote attacker when deserializing specially crafted sparse arrays. This could lead to excessive memory consumption, resulting in a Denial of Service (DoS) for the affected system." ],
  "statement" : "This vulnerability is rated as Important. The `devalue` JavaScript library is susceptible to excessive memory consumption. Deserializing specially crafted sparse arrays can lead to resource exhaustion and a denial of service, impacting the availability of affected systems.",
