OpenClaw before 2026.4.22 contains a security envelope constraint bypass vulnerability allowing restricted subagents to spawn ACP child sessions that fail to inherit depth, child-count limits, control scope, or target-agent restrictions. Attackers can exploit this by spawning child sessions that bypass subagent-only constraints, potentially escalating privileges or accessing restricted resources.
