CVE-2026-41398: OpenClaw: iOS A2UI bridge trusted generic local-network pages for agent.request dispatch

April 7, 2026 (updated April 28, 2026)

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.
