0 CVE-2026-29772 is a medium-severity vulnerability in the Astro web framework versions prior to 10.0.0. The issue arises from the Server Islands POST handler, which parses the entire request body as JSON without enforcing any size limits. This allows an attacker to send a crafted payload containing many small JSON objects, causing approximately 15 times memory amplification in the V8 JavaScript engine heap. As a result, a single unauthenticated request can exhaust the server's memory and crash the process, leading to denial of service. The vulnerable endpoint is /_server-islands/[name], which is registered on all Astro SSR apps using the Node standalone adapter, regardless of component usage. The vulnerability has been patched in Astro version 10.0.0. Join the discussion | CVE Database V5 | 03/24/2026, 18:38:02 UTC Added: 03/24/2026, 19:02:51 UTC |
