Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | @sveltejs/kit | < 2.57.1 | 2.57.1 |
Details
As written in the advisory (Markdown source, shown as plain text).
`redirect`, when called from inside the `handle` server hook with a location parameter containing characters that are invalid in a HTTP header, will cause an unhandled `TypeError`. This could result in DoS on some platforms, especially if the location passed to `redirect` contains unsanitized user input.
