From 10.0.3 until 11.0.3, the Astro Vercel adapter in packages/integrations/vercel/src/serverless/entrypoint.ts accepts x_astro_path for the public /_isr function based only on the x-vercel-isr header, allowing unauthenticated GET requests to render routes protected only by Vercel edge path rules or split edge middleware. This issue is fixed in 11.0.3."

Desde la versión 10.0.3 hasta la 11.0.3, el adaptador de Astro Vercel en packages/integrations/vercel/src/serverless/entrypoint.ts acepta x_astro_path para la función pública /_isr basándose únicamente en el encabezado x-vercel-isr, permitiendo que solicitudes GET no autenticadas rendericen rutas protegidas solo por reglas de ruta de borde de Vercel o middleware de borde dividido. Este problema está solucionado en la versión 11.0.3."
