Technical details
The vulnerability exists in the sandbox browser CDP relay (socat) configuration, which bound to 0.0.0.0 inside the container without enforcing source-range restrictions by default. While host-side binding was already restricted to 127.0.0.1, peer containers on the same Docker bridge network could reach the relay unauthenticated. The root cause is that the CDP_SOURCE_RANGE environment variable was optional and defaulted to empty. The fix enforces mandatory source-range restriction by auto-deriving it from the Docker network gateway IP and refusing to start the socat relay without one. For bridge-style networks, the gateway IP is automatically detected; for non-bridge drivers (macvlan, ipvlan, overlay), explicit configuration is required. The patch is available in openclaw 2026.4.10 and later.
