Miggo AIRoot Cause Analysis

The vulnerability stems from Swauth middleware using raw authentication tokens as part of object names in Swift paths. These paths are logged by Swift's proxy/object servers. The pre-patch code in middleware.py directly embedded tokens in paths via string formatting (e.g., '/v1/%s/.token_%s/%s' % (auth_account, token[-1], token)). The commit 70af798 introduced _get_concealed_token() to hash tokens before path construction, explicitly fixing these four functions where raw tokens were used. The functions' direct involvement in token path creation and the explicit patch modifications confirm their vulnerability.
