Machine-written summary

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

Cachet versions before 2.5.1 are vulnerable. An authenticated user with any role, including a regular User, can trick the application into reinstalling the instance, which can lead to arbitrary code execution on the server. Upgrade to Cachet 2.5.1 or later; as a workaround, allow only trusted IP addresses to reach the administration dashboard.
