In versions >= 2026.7.1 and < 2026.8.1, Synology Chat attachment delivery could lose DNS pinning: the Gateway validated a single DNS result for a supplied file URL but then passed the original hostname to the Synology NAS, where it could resolve to a different destination. When attachment delivery accepted a remotely influenced hostname, an attacker could use DNS rebinding to make the NAS fetch a private or otherwise policy-denied resource and return its contents to the addressed conversation (server-side request forgery). Practical impact depends on NAS routing, resolver behavior, and the response available at the private destination. The issue is fixed in 2026.8.1; as a workaround, disable remote URL attachment forwarding in Synology Chat.","evidence":"cve:CVE-2026-100555","products":[{"name":{"value":"OpenClaw","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"high","structured":{"id":"CVE-2026-100555","aliases":["CVE-2026-100555"],"metrics":[{"format":"CVSS","cvssV4_0":{"version":"4.0","baseScore":7.1,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:H/VI:L/VA:N/SC:H/SI:L/SA:N","userInteraction":"NONE","attackComplexity":"HIGH","attackRequirements":"PRESENT","privilegesRequired":"LOW","subIntegrityImpact":"LOW","vulnIntegrityImpact":"LOW","subAvailabilityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"HIGH","vulnConfidentialityImpact":"HIGH"}},{"format":"CVSS","cvssV3_1":{"scope":"CHANGED","version":"3.1","baseScore":7.1,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:L/A:N","integrityImpact":"LOW","userInteraction":"NONE","attackComplexity":"HIGH","availabilityImpact":"NONE","privilegesRequired":"LOW","confidentialityImpact":"HIGH"}}],"affected":[{"vendor":"OpenClaw","product":"OpenClaw","versions":[{"status":"affected","version":"2026.7.1","lessThan":"2026.8.1","versionType":"semver"},{"status":"unaffected","version":"2026.8.1","versionType":"semver"}],"packageURL":"pkg:npm/openclaw","defaultStatus":"unaffected"}],"modified":"2026-10-05T14:55:03.826Z","provider":"cve","references":["https://github.com/openclaw/openclaw/security/advisories/GHSA-cf95-m4jv-59rc","https://www.vulncheck.com/advisories/openclaw-before-2026.8.1-dns-rebinding-via-attachment-delivery"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-100555","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-10-05T14:04:24.718338Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-05T14:55:03.826Z"}}],"cna":{"orgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","shortName":"VulnCheck","dateUpdated":"2026-09-26T02:18:49.708Z"}}},"related_cves":[{"value":"CVE-2026-100555","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":8654,"next_before":8654}
