A later browser evaluation could then read from the page reached by that action-triggered navigation.\n\nThis issue is specific to browser control actions and private-network navigation policy. Browser evaluation remains an intentional trusted-operator feature when it is used on pages that policy allowed the browser to visit.\n\n### Affected configurations\n\nThis affects deployments where browser control is enabled and an authenticated browser-control caller can interact with an attacker-controlled page that redirects or navigates the tab to a private-network target through a UI action.\n\n### Impact\n\nIf the browser reached a private page through an unchecked action-triggered navigation, a caller with browser evaluation capability could read page content that direct navigation policy would have blocked.\n\nThe issue does not grant access to OpenClaw without authentication. It bypasses the private-network navigation guard for a specific browser action path.\n\n### Patched Versions\n\nThe first stable patched version is `2026.5.18`.\n\n### Mitigations\n\nUpgrade to `openclaw@2026.5.18` or later. Before upgrading, restrict browser-control access to trusted operators and avoid using browser control on untrusted pages in environments with sensitive private web services.\n\n## Affected packages\n\n- `openclaw < 2026.5.18`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `openclaw 2026.5.18`","depth":"sunlit","depthScore":42,"depthScoreParts":{"impact":42.4,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
