{"id":"CVE-2026-53812","aliases":["GHSA-2hfg-4fh4-qp7f"],"url":"https://o3.security/vulnerability/CVE-2026-53812","summary":"OpenClaw < 2026.5.18 - Private-Network Navigation Bypass via Browser Act Interactions","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.","published":"2026-06-11T20:07:51.760Z","modified":"2026-08-17T03:55:02.689621116Z","cvss":null,"epss":{"score":0.00247,"percentile":0.16138,"asOf":"2026-09-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.5.18"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53812.json"},{"type":"ADVISORY","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":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-private-network-navigation-bypass-via-browser-act-interactions"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-17T03:55:02.689621116Z"}}
