Allocation of Resources Without Limits or Throttling

Overview @sveltejs/kit is a SvelteKit framework and CLI Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the deserializebinaryform function in the remote form handler. An attacker can exhaust application resources by sending crafted bina...

SvelteKit has deserialization expansion in unvalidated `form` remote function leading to Denial of Service (experimental only)

Some relatively small inputs can cause very large files arrays in form handlers. 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. Only users with experimental.remoteFunctions:...
