CVE-2026-35662
OpenClaw < 2026.3.22 - Missing controlScope Enforcement in Send Action
OpenClaw before 2026.3.22 fails to enforce controlScope restrictions on the send action, allowing leaf subagents to message controlled child sessions beyond their authorized scope. Attackers can exploit this by using the send action to communicate with child sessions without proper scope validation, bypassing intended access control restrictions.
