CVE-2026-112346
OpenHands Software Agent SDK < 1.52.0 Unauthenticated Sandbox Agent Server RCE
OpenHands Software Agent SDK before 1.52.0 contains an unauthenticated remote code execution vulnerability where the DockerWorkspace and Apptainer workspace launchers bind the sandbox agent server to all network interfaces (0.0.0.0) with an empty session_api_keys list, disabling authentication by default. Attackers who can reach the published container port can send unauthenticated HTTP and WebSocket requests to execute arbitrary shell commands as root in the sandbox, access the mounted workspace, and read plaintext secrets from the secrets store.
