SCA: security update for @sveltejs/kit (GHSA-gv7g-x59x-wf8f)

high Tenable Cloud Security Plugin ID 415300

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - The SvelteKit framework offers developers an option to create simple REST APIs. This is done by defining a
 `+server.js` file, containing endpoint handlers for different HTTP methods. SvelteKit provides out-of-the-
 box cross-site request forgery (CSRF) protection to its users. The protection is implemented at
 `kit/src/runtime/server/respond.js`. While the implementation does a sufficient job of mitigating common
 CSRF attacks, the protection can be bypassed in versions prior to 1.15.2 by simply specifying an upper-
 cased `Content-Type` header value. The browser will not send uppercase characters, but this check does not
 block all expected CORS requests. If abused, this issue will allow malicious requests to be submitted from
 third-party domains, which can allow execution of operations within the context of the victim's session,
 and in extreme scenarios can lead to unauthorized access to users’ accounts. This may lead to all POST
 operations requiring authentication being allowed in the following cases: If the target site sets
 `SameSite=None` on its auth cookie and the user visits a malicious site in a Chromium-based browser; if
 the target site doesn't set the `SameSite` attribute explicitly and the user visits a malicious site with
 Firefox/Safari with tracking protections turned off; and/or if the user is visiting a malicious site with
 a very outdated browser. SvelteKit 1.15.2 contains a patch for this issue. It is also recommended to
 explicitly set `SameSite` to a value other than `None` on authentication cookies especially if the upgrade
 cannot be done in a timely manner. (CVE-2023-29008)
