You should be able to search for cases by SSN, but documents should have all but the last 4 digits redacted/blacked out. If there is a document (e.g. paystub) that is included and displays your entire SSN, you should address this. If you work with an attorney, he or she may have uploaded a document without redacting the SSN.
Otherwise, more details would be helpful to determine what you are referring to.
