PTC has addressed three Cross Site Scripting Issues.

Updated to the latest PostgreSQL driver version to 42.2.5. Action may be required if you are using .ssl on the jdbc connection string due to the driver change that has a new default of sslmode=verify-full. The previous default was sslmode=prefer. See https://www.postgresql.org/about/news/1883/ for details around this change.
The implications are that verify-full will now validate against a root certificate, and if a root certificate is not configured, the connection to PostgreSQL will fail.
jdbc:postgresql://localhost:5432/thingworx?ssl=true
To set up the secure default, you must set up a root certificate. Azure instructions can be found here: https://docs.microsoft.com/en-us/azure/postgresql/concepts-ssl-connection-security
For more details about how the driver works with a root certificate, see https://www.postgresql.org/docs/9.4/libpq-ssl.html
