Aliases CVE-2026-41398
Summary OpenClaw: iOS A2UI bridge trusted generic local-network pages for agent.request dispatch ## 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. ## Affected Packages / Versions - Package: openclaw (npm) - Affected versions: <= 2026.4.1 - Patched versions: >= 2026.4.2 - Latest published npm version: 2026.4.1 ## Fix Commit(s) 49d08382a90f71dabe2877b3f6729ad85f808d57 — restrict A2UI action dispatch to trusted canvas URLs ## Release Process Note The fix is present on main and is staged for OpenClaw 2026.4.2. Publish this advisory after the 2026.4.2 npm release is live. Thanks [@nexrin](https://github.com/nexrin) for reporting.
