> DESCRIPTION

Astro is a web framework for content-driven websites. 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.

CWE-441 CWE-862

> CWE DETAILED DESCRIPTIONS

CWE-441: Unintended Proxy or Intermediary ('Confused Deputy') - The product receives a request, message, or directive from an upstream component, but the product does not sufficiently preserve the original source of the request before forwarding the request to an external actor that is outside of the product's control sphere. This causes the product to appear to be the source of the request, leading it to act as a proxy or other intermediary between the upstream component and the external actor. | CWE-862: Missing Authorization - The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
