Description (CNA)
Svelte devalue is a JavaScript library that serializes values into strings when JSON.stringify isn't sufficient for the job. From 5.1.0 to 5.6.1, certain inputs can cause devalue.parse to consume excessive CPU time and/or memory, potentially leading to denial of service in systems that parse input from untrusted sources. This affects applications using devalue.parse on externally-supplied data. The root cause is the ArrayBuffer hydration expecting base64 encoded strings as input, but not checking the assumption before decoding the input. This vulnerability is fixed in 5.6.2.

A flaw was found in devalue, a JavaScript library used for serializing values. A remote attacker could exploit this vulnerability by providing specially crafted input to the `devalue.parse` function. This improper input validation, specifically during the ArrayBuffer hydration process, can cause the application to consume excessive CPU time and memory. This ultimately leads to a denial of service (DoS), making the affected system unavailable to legitimate users.
