Title

OpenClaw - Unauthorized Agent Request Dispatch via Untrusted Local-Network Pages in iOS A2UI Bridge

Summary

OpenClaw before 2026.4.2 contains an improper access control vulnerability in the iOS A2UI bridge that treats generic local-network pages as trusted origins. Attackers can inject unauthorized agent.request runs by loading attacker-controlled pages from local-network or tailnet hosts, polluting session state and consuming budget.

BREW-OPENCLAW-CLI-CVE-20… (GHSA-4P4F-FC8Q-84M3)

Vulnerability from osv_homebrew – Published: 2026-08-13 17:21 – Updated: 2026-09-25 08:57 – Source website

Summary

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

Details

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 for reporting.

A page loaded from a local-network or tailnet host could trigger agent.request dispatch without the stricter trusted-canvas origin check.\n\n## Impact\nA 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.\n\n## Affected Packages / Versions\n- Package: openclaw (npm)\n- Affected versions: \u003c= 2026.4.1\n- Patched versions: \u003e= 2026.4.2\n- Latest published npm version: 2026.4.1\n\n## Fix Commit(s)\n49d08382a90f71dabe2877b3f6729ad85f808d57 \u2014 restrict A2UI action dispatch to trusted canvas URLs\n\n## Release Process Note\nThe 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.\n\nThanks [@nexrin](https://github.com/nexrin) for reporting.",
