GHSA-2858-xg23-26fp: OpenClaw: Node camera URL payload host-binding bypass allowed gateway fetch pivots

OpenClaw accepted camera.snap / camera.clip node payload url fields and downloaded them on the gateway/agent host without binding downloads to the resolved node host.

In OpenClaw’s documented trust model, paired nodes are in the same operator trust boundary, so this is scoped as medium-severity hardening. A malicious or compromised paired node could still steer gateway-host fetches during camera URL retrieval.
