GitHub Vulnerability Alerts

GHSA-vrhm-gvg7-fpcf

Versions of @sveltejs/kit prior to 2.52.2 with remote functions enabled can be vulnerable to memory exhaustion. Malformed form data can cause the server process to crash due to excessive memory allocation, resulting in denial of service.

Only applications using both experimental.remoteFunctions and form are vulnerable.

GHSA-88qp-p4qg-rqm6

Versions of @sveltejs/kit prior to 2.52.2 with remote functions enabled are vulnerable to CPU exhaustion. Malformed form data can cause the server to become unresponsive while processing a request, resulting in denial of service.

Only applications using both experimental.remoteFunctions and form are vulnerable.

GHSA-fpg4-jhqr-589c

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: true who are using the form function and are processing the files array without validation are vulnerable.

v2.51.0

Compare Source

Minor Changes

• feat: add scroll property to NavigationTarget in navigation callbacks (#​15248)

  Navigation callbacks (beforeNavigate, onNavigate, and afterNavigate) now include scroll position information via the scroll property on from and to targets:

  • from.scroll: The scroll position at the moment navigation was triggered
  • to.scroll: In beforeNavigate and onNavigate, this is populated for popstate navigations (back/forward) with the scroll position that will be restored, and null for other navigation types. In afterNavigate, this is always the final scroll position after navigation completed.

  This enables use cases like animating transitions based on the target scroll position when using browser back/forward navigation.
