CVE-2026-22775 (opens in a new tab)How to fix?
Upgrade devalue to version 5.6.2 or higher.
Overview
devalue is a JSON.stringify, but handles cyclical references, repeated references, undefined, regular expressions, dates, Map and Set.
Affected versions of this package are vulnerable to Asymmetric Resource Consumption (Amplification) due to the improper validation in ArrayBuffer if input string is base64 encoded in the hydration() function when parsing data from untrusted sources. An attacker can cause excessive memory allocation and CPU usage by submitting specially crafted input, potentially leading to resource exhaustion and service disruption.
