Kerentanan Use of Non-Canonical URL Paths for Authorization Decisions pada astro. Skor CVSS 3.1 6.5 (Medium) menurut NVD.

Deskripsi (NVD)

Astro is a web framework. Versions 5.15.7 and below have a double URL encoding bypass which allows any unauthenticated attacker to bypass path-based authentication checks in Astro middleware, granting unauthorized access to protected routes. While the original CVE-2025-64765 was fixed in v5.15.8, the fix is insufficient as it only decodes once. By using double-encoded URLs, attackers can still bypass authentication and access any route protected by middleware pathname checks. This issue is fixed in version 5.15.8.
