  3. CVE-2026-27901
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.

Summary
  • (es) Framework web Svelte orientado al rendimiento. Antes de la versión 5.53.5, el contenido de `bind:innerText` y `bind:textContent` en elementos `contenteditable` no se escapaba correctamente. Esto podría permitir la inyección de HTML y cross-site scripting (XSS) si se renderizaban datos no confiables como el valor inicial del enlace en el servidor. La versión 5.53.5 corrige el problema.
