CVE-2026-42570

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.
