CVE-2026-27646: OpenClaw: Sandboxed /acp spawn requests could initialize host ACP sessions
(updated )
Sandboxed requester sessions could reach host-side ACP session initialization through /acp spawn.
OpenClaw already blocked sessions_spawn({ runtime: "acp" }) from sandboxed sessions, but the slash-command path initialized ACP directly without applying the same host-runtime guard first.
