Описание

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.
