In versions >= 2026.4.5 and < 2026.8.1, the Gateway validated a single DNS resolution result for a configured remote Chrome DevTools Protocol (CDP) hostname, but the raw WebSocket and Playwright transports performed a later, independent DNS resolution, discarding the DNS pinning enforced at validation time. An attacker who controls an approved CDP hostname or its DNS answers can exploit this check-then-use gap via DNS rebinding to make the Gateway connect to a loopback, private, link-local, cloud metadata, or other SSRF-policy-denied address. The impact depends on the remote CDP configuration, DNS timing, and the services reachable from the Gateway host. The issue is fixed in 2026.8.1; as a mitigation, disable hostname-based remote CDP endpoints or restrict them to trusted, stable infrastructure.","state":0,"publishedAt":"2026-09-26T02:18:57.448+00:00","modifiedAt":"2026-09-28T17:36:49.515+00:00","affected":[{"ecosystem":"Vendor product","name":"OpenClaw","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"OpenClaw\",\n                    \"product\": \"OpenClaw\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:npm/openclaw\",\n                    \"versions\": [\n                        {\n                            \"version\": \"2026.4.5\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"2026.8.1\"\n                        },\n                        {\n                            \"version\": \"2026.8.1\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:H/VI:H/VA:L/SC:H/SI:H/SA:L","score":8.9,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:L","score":8.2,"severity":"HIGH"}],"references":["https://github.com/openclaw/openclaw/security/advisories/GHSA-p3h6-v2h4-36q2","https://www.vulncheck.com/advisories/openclaw-before-2026.8.1-dns-rebinding-via-cdp-hostname"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100567","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100567","identifiers":["CVE-2026-100567"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
