In versions \u003e= 2026.4.5 and \u003c 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.","severity":{"version":"4.0","score":8.9,"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","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-12","score":0.00253,"percentile":0.17013,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-918"],"published":"2026-09-26T02:18:57Z","modified":"2026-10-28T02:30:20Z","products":[{"vendor":"openclaw","product":"openclaw"}],"references":[{"url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-p3h6-v2h4-36q2","tags":["vendor-advisory","advisory"]},{"url":"https://www.vulncheck.com/advisories/openclaw-before-2026.8.1-dns-rebinding-via-cdp-hostname","tags":["third-party-advisory","advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-100567","tags":["advisory"]},{"url":"https://github.com/advisories/GHSA-px74-p6x8-q327"},{"url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/100xxx/CVE-2026-100567.json","tags":["advisory"]}],"sources":{"cve":[{"id":"CVE-2026-100567","title":"OpenClaw before 2026.8.1 DNS Rebinding via CDP Hostname","description":"OpenClaw is an agent gateway distributed as the npm package 'openclaw'.
