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

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.
