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.","state":0,"publishedAt":"2026-09-26T02:18:49.708+00:00","modifiedAt":"2026-10-05T14:55:03.826+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\": \"2026.7.1\",\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:L/UI:N/VC:H/VI:L/VA:N/SC:H/SI:L/SA:N","score":7.1,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:L/A:N","score":7.1,"severity":"HIGH"}],"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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100555","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100555","identifiers":["CVE-2026-100555"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
