Technical Analysis
The OpenClaw CLI vulnerability (CVE-2026-35662) involves leaf subagents bypassing controlScope restrictions to send messages to child sessions even when their controlScope does not permit such actions. The flaw was addressed by threading the controller context through the send path and blocking send attempts unless the requester owns the target and has controlScope set to "children". The fix was introduced in version 2026.3.22.
Potential Impact
This vulnerability allows leaf subagents to send messages to child sessions despite controlScope restrictions, potentially leading to unauthorized message sending within the OpenClaw CLI environment. The CVSS score of 4.3 (medium severity) reflects limited impact on confidentiality and no impact on availability or critical integrity loss.
Mitigation Recommendations
A fix is available and was shipped in OpenClaw CLI version 2026.3.22. Users should upgrade to version 2026.3.22 or later to remediate this vulnerability.
