Node revocation invalidates the WebSocket client, but Canvas HTTP authorization continues to accept and renew the previously granted capability until WebSocket close cleanup completes. As a result, a revoked paired node can continue exercising its Canvas capability against the capability's configured routes during the close grace period. The issue is fixed in 2026.8.1; as a workaround, restart the Gateway after revoking a node that has Canvas access.","evidence":"cve:CVE-2026-100554","products":[{"name":{"value":"OpenClaw","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"medium","structured":{"id":"CVE-2026-100554","aliases":["CVE-2026-100554"],"metrics":[{"format":"CVSS","cvssV4_0":{"version":"4.0","baseScore":2.3,"attackVector":"NETWORK","baseSeverity":"LOW","vectorString":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","userInteraction":"NONE","attackComplexity":"HIGH","attackRequirements":"PRESENT","privilegesRequired":"LOW","subIntegrityImpact":"NONE","vulnIntegrityImpact":"LOW","subAvailabilityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","vulnConfidentialityImpact":"LOW"}},{"format":"CVSS","cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":4.2,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","integrityImpact":"LOW","userInteraction":"NONE","attackComplexity":"HIGH","availabilityImpact":"NONE","privilegesRequired":"LOW","confidentialityImpact":"LOW"}}],"affected":[{"vendor":"OpenClaw","product":"OpenClaw","versions":[{"status":"affected","version":"2026.5.12","lessThan":"2026.8.1","versionType":"semver"},{"status":"unaffected","version":"2026.8.1","versionType":"semver"}],"packageURL":"pkg:npm/openclaw","defaultStatus":"unaffected"}],"modified":"2026-09-28T17:38:43.352Z","provider":"cve","references":["https://github.com/openclaw/openclaw/security/advisories/GHSA-g697-vv6h-r8hv","https://www.vulncheck.com/advisories/openclaw-before-2026.8.1-canvas-capability-revocation-bypass"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-100554","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-28T17:38:32.165169Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-28T17:38:43.352Z"}}],"cna":{"orgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","shortName":"VulnCheck","dateUpdated":"2026-09-26T02:18:49.013Z"}}},"related_cves":[{"value":"CVE-2026-100554","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":3250,"next_before":3250}
