CVE-2026-42570 · Svelte devalue: DoS via sparse array deserialization
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
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.
