Description
Paperclip before 0.3.1 in default local_trusted mode fails to validate Host headers, allowing attackers to execute arbitrary commands via DNS rebinding. An attacker can craft a malicious webpage that, when visited by a developer running Paperclip locally, uses DNS rebinding to make authenticated API requests and execute commands through the process adapter.
