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.","state":0,"publishedAt":"2026-09-26T02:18:49.013+00:00","modifiedAt":"2026-09-28T17:38:43.352+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\": \"2026.5.12\",\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:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":2.3,"severity":"LOW"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","score":4.2,"severity":"MEDIUM"}],"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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100554","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100554","identifiers":["CVE-2026-100554"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
