{"id":"GHSA-2hfg-4fh4-qp7f","summary":"OpenClaw's browser act interactions could bypass private-network navigation checks","details":"### Summary\n\nOpenClaw's browser control SSRF checks blocked direct navigation to private or loopback URLs, but some Playwright `act` interactions could trigger navigation after the initial check. 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.","aliases":["CVE-2026-53812"],"modified":"2026-07-02T16:26:33.110376Z","published":"2026-07-02T16:00:03Z","database_specific":{"github_reviewed_at":"2026-07-02T16:00:03Z","nvd_published_at":"2026-06-11T21:16:23Z","cwe_ids":["CWE-284","CWE-918"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-2hfg-4fh4-qp7f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53812"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-private-network-navigation-bypass-via-browser-act-interactions"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.5.18"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-2hfg-4fh4-qp7f/GHSA-2hfg-4fh4-qp7f.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N"}]}
