PerfreeBlog v4.0.11 is vulnerable to Server-Side Request Forgery due to a missing authorization check in the uploadAttachByUrl API endpoint (AttachController.java).
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
