CVE-2026-33769 · Astro: Remote allowlist bypass via unanchored matchPathname wildcard
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
Astro is a web framework. From version 2.10.10 to before version 5.18.1, this issue concerns Astro's remotePatterns path enforcement for remote URLs used by server-side fetchers such as the image optimization endpoint. The path matching logic for /* wildcards is unanchored, so a pathname that contains the allowed prefix later in the path can still match. As a result, an attacker can fetch paths outside the intended allowlisted prefix on an otherwise allowed host. This issue has been patched in version 5.18.1.
