CVE-2026-54299

Astro is a web framework. Prior to 6.4.6, Astro SSR apps with prerendered error pages /404 or /500 using export const prerender = true fetch those pages over HTTP at runtime when an error occurs. The URL for this fetch is derived from request.url, which in turn gets its origin from the incoming...

CVE-2026-55602

http-proxy-middleware is node.js http-proxy middleware. From 0.16.0 until 2.0.10, 3.0.6, and 4.1.0, http-proxy-middleware documents router proxy-table entries as host, path, or host+path selectors, but the host+path implementation uses unanchored substring matching on attacker-controlled request...

CVE-2026-54299

Summary of CVE-2026-54299 (Astro) : Astro SSR apps that prerender error pages (e.g., 404/500 with prerender = true) fetch those pages over HTTP using a URL derived from request.url, which is based on the Host header. If Host is not validated against allowedDomains, an attacker can direct the fetc...
