Description
NanoClaw before 2.1.0 contains a privilege escalation vulnerability in the channel-registration approval flow where handleChannelApprovalResponse fails to validate admin privileges over target agent groups. Scoped admins can submit forged or stale connect callback values to wire messaging channels into out-of-scope agent groups, exposing unauthorized groups to unapproved channels and enabling unauthorized observation or control of restricted agent group activity.
