Cognition before 0.13.0 contains an unauthenticated remote code execution vulnerability due to defaulting its agent sandbox backend to local execution and shipping no authentication on its REST/SSE API. Attackers can create a session via POST /sessions and post a message via POST /sessions/{id}/messages without credentials, causing the Deep Agents ReAct loop to run attacker-directed shell commands through the local shell backend, resulting in remote code execution as the server process.
Cognition < 0.13.0Upgrade to Cognition 0.13.0 or later. Version 0.13.0 refuses the local sandbox backend unless COGNITION_ALLOW_UNSAFE_LOCAL_EXECUTION is explicitly set to true, and that setting defaults to false.
