Summary
MantisBT has an authorization bypass that allows reading attachments after losing access to a private issue
Details

MantisBT permits a user to list and download their own attachments from an Issue created by another user, even after that Issue becomes private and direct access to it is denied.

Impact

The loss of confidentiality caused by this vulnerability is minimal, considering that only the attachments that were previously uploaded by the user themselves remains accessible.
