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.","evidence":"cve:CVE-2026-100553","products":[{"name":{"value":"OpenClaw","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"medium","structured":{"id":"CVE-2026-100553","aliases":["CVE-2026-100553"],"metrics":[{"format":"CVSS","cvssV4_0":{"version":"4.0","baseScore":5.3,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"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","userInteraction":"NONE","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"LOW","subIntegrityImpact":"NONE","vulnIntegrityImpact":"LOW","subAvailabilityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","vulnConfidentialityImpact":"NONE"}},{"format":"CVSS","cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":4.3,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","integrityImpact":"LOW","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"LOW","confidentialityImpact":"NONE"}}],"affected":[{"vendor":"OpenClaw","product":"OpenClaw","versions":[{"status":"affected","version":"2026.6.9","lessThan":"2026.8.1","versionType":"semver"},{"status":"unaffected","version":"2026.8.1","versionType":"semver"}],"packageURL":"pkg:npm/openclaw","defaultStatus":"unaffected"}],"modified":"2026-09-29T17:10:13.838Z","provider":"cve","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"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-100553","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-29T17:09:47.857552Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-29T17:10:13.838Z"}}],"cna":{"orgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","shortName":"VulnCheck","dateUpdated":"2026-09-26T02:18:48.240Z"}}},"related_cves":[{"value":"CVE-2026-100553","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":3853,"next_before":3853}
