Security Advisories 🚨

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

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.

🚨 Svelte: XSS via HTML Comment Injection in SSR Error Boundary Hydration Markers

Errors from transformError were not correctly escaped prior to being embedded in the HTML output, causing potential HTML injection and XSS if attacker-controlled content is returned from transformError.
