GHSA-88f9-7xxh-c688 Cachet configuration leak

• Packagist cachethq/cachet: < 2.5.1 → fixed in 2.5.1

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.
