Executive Summary

This vulnerability affects Arcane, an interface for managing Docker environments. Before version 1.13.2, unauthenticated requests could be proxied to remote environment agents, allowing attackers to access remote environment resources without authentication. The middleware handling environment proxy requests would forward requests with a manager-held agent token even if the requester was unauthenticated, enabling unauthorized access to operations like listing containers or streaming logs on remote environments.
