Cachet configuration leak

Impact

Authenticated users, regardless of their privileges (User or Admin), can leak the value of any configuration entry of the dotenv file, e.g. the application secret (APP_KEY) and various passwords (email, database, etc).

Patches

This issue was addressed by improving UpdateConfigCommandHandler and preventing the use of nested variables in the resulting dotenv configuration file.

Workarounds

Only allow trusted source IP addresses to access to the administration dashboard.
