CVE-2026-27901

Svelte vulnerable to XSS during SSR with contenteditable `bind:innerText` and `bind:textContent`

Svelte performance oriented web framework. Prior to version 5.53.5, the contents of `bind:innerText` and `bind:textContent` on `contenteditable` elements were not properly escaped. This could enable HTML injection and Cross-Site Scripting (XSS) if rendering untrusted data as the binding's initial value on the server. Version 5.53.5 fixes the issue.
