CVE-2026-73424 · Astro: Unauthenticated path override in the @astrojs/vercel ISR function
This page contains facts from public vulnerability sources. Check the original advisory before updating.
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.
