Unauthenticated internal service access via unchecked attachment URL
Published Oct 30, 2025 · Updated Oct 30, 2025
Server-side request forgery in PerfreeBlog 4.0.11 allows remote attackers to make server-side requests through the attachment API. The uploadAttachByUrl handler passes the request body's URL directly to attachService.uploadAttachByUrl without checking authorization, causing the server to fetch attacker-selected destinations. No authentication is required in the default production configuration, enabling internal port scans and access to services reachable from the host.
