Overview
@astrojs/vercel is a Deploy your site to Vercel
Affected versions of this package are vulnerable to Missing Authorization via the _isr process. An attacker can access protected content by sending unauthenticated GET requests with a crafted x_astro_path query parameter, causing the server to render and return any route, even those protected by edge rules or middleware. This is only exploitable if edge-based access controls or middleware are used to protect routes, and the deployment uses split middleware or path-based rules at the edge.
