description

Affected versions of @sveltejs/kit can expose values intended for server-side use in browser-delivered bundles. Exposure requires an application to import server-only modules through src/params.js, allowing users who obtain the client bundle to inspect included values.

mitigation

Upgrade @sveltejs/kit to version 3.1.1 or later. Until upgraded, remove server-only imports from src/params.js and rotate any secrets that may have been included in deployed client bundles.

fixed in 3.1.1
