CyberRota Analysis

AI-Generated

Astro web framework versions prior to 7.2.4 are vulnerable to a pathname-based authorization bypass, allowing unauthenticated attackers to access protected routes by manipulating request pathnames. This vulnerability arises from improper handling of non-root base paths, potentially exposing sensitive application areas. Developers and security teams using affected versions should prioritize upgrading to 7.2.4 to mitigate the risk of unauthorized access.

Original NVD Description

Astro is a web framework for content-driven websites. Prior to 7.2.4, Astro stripped a configured non-root base path from request pathnames using a string-prefix check without verifying a path-segment boundary. With base "/app", a request to "/appX/admin" resolved internally to the protected "/admin" route while middleware observed "/appX/admin" in context.url.pathname. In applications that authorize base-prefixed routes by inspecting context.url.pathname, an unauthenticated remote attacker could bypass pathname-based middleware authorization and reach protected routes. This issue is fixed in version 7.2.4.
