Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Cachet versions before 2.5.1 (Packagist package cachethq/cachet) let any authenticated user, whether a regular User or an Admin, leak the value of any entry in the dotenv configuration file, such as the application secret APP_KEY and email, database and other passwords. Upgrade to Cachet 2.5.1 or later, which prevents nested variables in the generated dotenv file. As a workaround, restrict access to the administration dashboard to trusted IP addresses.
