Steps to Reproduce:

1. Log into JIRA
2. Log out from JIRA

Expected Results:

1. The URL shown in the address bar does not show the atl_token value

Actual Results:

1. The URL shown in the address bar shows the atl_token value

Impact

After checking with the security teams, this appears to be a low risk problem (as the token is invalid after logging out). However, if there are other resources where atl_token is used as a request parameter and a resource from an external resource is included then the referrer header will leak the token (in the request to the external resource).
