Summary
Before OpenClaw 2026.4.2, the iOS A2UI bridge treated generic local-network pages as trusted bridge origins. A page loaded from a local-network or tailnet host could trigger agent.request dispatch without the stricter trusted-canvas origin check.
Impact
A loaded attacker-controlled page could inject unauthorized non-owner agent.request runs into the active iOS node session, polluting session state and consuming budget. The demonstrated impact did not include owner-only actions or arbitrary host execution.
