If the SvelteKit application code doesn't check `files.length` or individual files' sizes and performs expensive processing with them, it can result in Denial of Service.\n\nOnly users with `experimental.remoteFunctions: true` who are using the `form` function and are processing the `files` array without validation are vulnerable.","state":0,"publishedAt":"2026-02-28T02:04:39+00:00","modifiedAt":"2026-08-29T03:55:36.1684822+00:00","affected":[{"ecosystem":"npm","name":"@sveltejs/kit","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.49.0"},{"kind":"fixed","version":"2.53.3"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"LOW"}],"references":["https://github.com/sveltejs/kit/security/advisories/GHSA-fpg4-jhqr-589c","https://github.com/sveltejs/kit/commit/faba869db3644077169bf5d7c6e41fd5f3d6c65e","https://github.com/sveltejs/kit","https://github.com/sveltejs/kit/releases/tag/@sveltejs/kit@2.53.3"],"sourceUrl":"https://github.com/advisories/GHSA-fpg4-jhqr-589c","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-fpg4-jhqr-589c","identifiers":["GHSA-fpg4-jhqr-589c","CVE-2026-82259"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
