{"id":"GHSA-c4qm-58hj-j6pj","summary":"OpenClaw: Browser snapshot and screenshot routes could expose internal page content after navigation","details":"## Summary\n\nBrowser snapshot and screenshot routes could expose internal page content after navigation.\n\n## Affected Packages / Versions\n\n- Package: `openclaw`\n- Ecosystem: npm\n- Affected versions: `\u003c 2026.4.14`\n- Patched versions: `\u003e= 2026.4.14`\n\n## Impact\n\nAuthenticated browser tool callers could use snapshot, screenshot, or tab routes that did not consistently validate the final browser target after route-driven navigation. In restrictive browser SSRF configurations this could expose content from internal or otherwise disallowed pages.\n\n## Technical Details\n\nThe fix re-checks browser snapshot, screenshot, and tab route results against the configured browser SSRF policy before returning page content. Regression coverage was added around snapshot/screenshot and tab-route flows.\n\n## Fix\n\nThe issue was fixed in #66040. The first stable tag containing the fix is `v2026.4.14`, and `openclaw@2026.4.14` includes the fix.\n\n## Fix Commit(s)\n\n- `b75ad800a59009fc47eaa3471410f69046150e59`\n- PR: #66040\n\n## Release Process Note\n\nUsers should upgrade to `openclaw` 2026.4.14 or newer. The latest npm release, `2026.4.14`, already includes the fix.\n\n## Credits\n\nThanks to @zsxsoft, with sponsorship from @KeenSecurityLab and @qclawer for reporting this issue.","aliases":["CVE-2026-42436"],"modified":"2026-05-08T01:50:44.878883Z","published":"2026-04-17T21:47:36Z","database_specific":{"cwe_ids":["CWE-862","CWE-918"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-04-17T21:47:36Z","nvd_published_at":"2026-05-05T12:16:18Z"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-c4qm-58hj-j6pj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42436"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/pull/66040"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/b75ad800a59009fc47eaa3471410f69046150e59"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-internal-page-content-exposure-via-browser-snapshot-and-screenshot-routes"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.4.14"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-c4qm-58hj-j6pj/GHSA-c4qm-58hj-j6pj.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:H/VI:N/VA:N/SC:L/SI:N/SA:N"}]}
