Name of the Vulnerable Software and Affected Versions Cachet versions prior to 2.5.1

Description Cachet is an open source status page system. Authenticated users, regardless of their privileges, 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). This issue was addressed by improving UpdateConfigCommandHandler and preventing the use of nested variables in the resulting dotenv configuration file. As a workaround, only allow trusted source IP addresses to access to the administration dashboard.

Recommendations For versions prior to 2.5.1, update to version 2.5.1 to resolve the issue. As a temporary workaround, consider restricting access to the administration dashboard to only trusted source IP addresses.
