Impact
When source-controller is configured to use an Azure SAS token when connecting to Azure Blob Storage, the token was logged along with the Azure URL when the controller encountered a connection error. An attacker with access to the source-controller logs could use the token to gain access to the Azure Blob Storage until the token expires.
Patches
This vulnerability was fixed in source-controller v1.2.5.
Workarounds
There is no workaround for this vulnerability except for using a different auth mechanism such as Azure Workload Identity.
