{"id":"CVE-2026-100567","summary":"OpenClaw before 2026.8.1 DNS Rebinding via CDP Hostname","details":"OpenClaw is an agent gateway distributed as the npm package 'openclaw'. 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.","aliases":["GHSA-p3h6-v2h4-36q2"],"modified":"2026-09-30T03:30:28.586809669Z","published":"2026-09-26T02:18:57.448Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/100xxx/CVE-2026-100567.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-918"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/100xxx/CVE-2026-100567.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-p3h6-v2h4-36q2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-100567"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-before-2026.8.1-dns-rebinding-via-cdp-hostname"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openclaw/openclaw","events":[{"introduced":"3e72c0352dde84a0bcb3aabafa99c2d4b12d1c46"},{"fixed":"ea806575e6450e4d1efdfc72c19f04be982a1b9b"}],"database_specific":{"extracted_events":[{"introduced":"2026.4.5"},{"fixed":"2026.8.1"}],"source":"AFFECTED_FIELD"}}],"versions":["release-publish/e11c566824b1-1787940135","release-publish/6ddb9f049fb3-1787938179","release-publish/2133a924eef0-1787945469","release-publish/b3986403ddb9-1787938102","release-publish/5cb2eee257bc-1787929714","release-publish/5cb2eee257bc-1787929587","release-publish/a84a915b67bd-1787933964","release-publish/404719374e60-1787933925","release-publish/491769bded58-1787929537","release-publish/62c77b0fb51c-1787927225","release-publish/17a1225314cd-1787924262","release-publish/468054f93c43-1787921799","release-publish/d5412d73acfb-1787906286","release-publish/bccb649077f0-1787900300","release-publish/a33c8a5c0ec6-1787896022","release-publish/4074a8b44d89-1787849600","release-publish/5090935817e3-1787842724","release-publish/38fd9ad6e417-1787824804","release-publish/1c80cf86cfd0-1787823217","release-publish/21b41efc7bb8-1787818100","release-publish/8afa8f339eb6-1787798436","release-publish/ebc70fa1b3f6-1787634336","release-publish/c96e81375014-1787462685","release-publish/c28c279afa37-1787225611","release-publish/45ed68e6ea62-1787220256","release-publish/abd63c06c2f5-1786646045","release-publish/57fabb2c9c35-1786621048","release-publish/8371831eba5e-1786610071","release-publish/716f996be8db-1786550775","release-publish/f4987deb94b8-1786361493","release-publish/10a390ed7fa8-20260802","release-publish/5dca33a8fb67-20260802","release-publish/9bc3c2955500-20260802","release-publish/eb8c22ed13f9-20260801","release-publish/728084497329-20260801","release-publish/deffca656500-20260801","release-publish/7c9794b5c65c-20260801","release-publish/556a2ee276f0-20260718","release-publish/ced50f88e928-20260717","release-publish/a9ac13b2efd7-20260717","release-publish/8858944a81c5-20260717","release-publish/73d04395defe-20260717","release-publish/08987d8f409b-20260717","release-publish/d8dd59bf8f60-20260717","release-publish/0e9db6005954-20260717","release-publish/0e9db600595-20260717","release-publish/9b80f9a8b1df-20260717","release-publish/d8b3e1c093f2-20260715","release-publish/c3927271fad7-20260715","release-publish/23d2f664fb75-20260715","release-publish/f4f5bb15d46a-20260715","release-publish/1d2777548d01-20260715","release-publish/0f7fbfa0039f-20260715","release-publish/54f70c5d8c04-20260715","release-publish/dfa246e6fd16-20260715","release-publish/bb1a7e506927-20260715","v2026.4.19-beta.2","v2026.4.19-beta.1","v2026.4.15","v2026.4.15-beta.2","v2026.4.15-beta.1","v2026.4.14","v2026.4.14-beta.1","v2026.4.12","v2026.4.12-beta.1","v2026.4.11","v2026.4.11-beta.1","v2026.4.10","v2026.4.9","v2026.4.9-beta.1","v2026.4.8","v2026.4.7-1","v2026.4.7","v2026.4.5"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-100567.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
