When groupPolicy is set to allowlist, a missing or unsupported configured access group produces a denied group-resolution result that is not rejected by the final message-admission check, so a Teams member who is not on the allowlist can still trigger the configured agent despite the administrator's group boundary. The impact depends on the conversations, tools, and data available to that agent. The issue is fixed in version 2026.8.1.","state":0,"publishedAt":"2026-09-26T02:18:45.885+00:00","modifiedAt":"2026-09-28T17:33:57.811+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\": \"0\",\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:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":5.3,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/openclaw/openclaw/security/advisories/GHSA-8938-r7c6-54vq","https://www.vulncheck.com/advisories/openclaw-before-2026.8.1-authentication-bypass-via-access-group"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100550","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100550","identifiers":["CVE-2026-100550"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
