When tools.message.crossContext.allowWithinProvider is disabled, an admitted (authenticated) sender can remove a pin from another Feishu group that the sender and the configured account are otherwise permitted to access, bypassing the intended cross-context message mutation policy. Feishu membership and group authorization still apply, and the demonstrated impact is limited to message mutation (pin removal). The issue is fixed in 2026.8.1.","state":0,"publishedAt":"2026-09-26T02:18:48.24+00:00","modifiedAt":"2026-09-29T17:10:13.838+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\": \"2026.6.9\",\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:N/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:N/I:L/A:N","score":4.3,"severity":"MEDIUM"}],"references":["https://github.com/openclaw/openclaw/security/advisories/GHSA-h9jh-75j7-7hhx","https://www.vulncheck.com/advisories/openclaw-2026.6.9-before-2026.8.1-cross-context-policy-bypass-via-feishu-unpin"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100553","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100553","identifiers":["CVE-2026-100553"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
