CVE-2026-22774

CVE-2026-22774 affects the Svelte devalue library. From versions 5.3.0 through 5.6.1, certain inputs trigger devalue.parse to consume excessive CPU time and memory when processing untrusted data, potentially causing denial of service. Root cause: typed array hydration assumes an ArrayBuffer input...

CVE-2026-22774

Svelte devalue is a JavaScript library that serializes values into strings when JSON.stringify isn't sufficient for the job. From 5.3.0 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 inpu...
