Description

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

 - An SSR XSS exists in async hydration when attacker‑controlled keys are passed to hydratable. The key is
 embedded inside a <script> block without HTML‑safe escaping, allowing </script> to terminate the script
 and inject arbitrary JavaScript. This enables remote script execution in users' browsers, with potential
 for session theft and account compromise. This issue affects Svelte: from 5.46.0 before 5.46.3.
