In Gateway deployments using authentication modes that honor caller identity and narrower operator scopes, a write-scoped non-owner caller can start a chat turn whose tool inventory includes the `gateway` and `cron` tools, causing the agent to invoke owner-only configuration or scheduling operations, including persistent state changes. Practical impact depends on the tools selected by the model and the caller's ability to steer the turn. Shared-secret token and password callers are treated as fully trusted operators under OpenClaw's security model and are outside the scope of this issue. The issue is fixed in 2026.7.1; as a workaround, restrict chat.send to administrators in identity-bearing deployments and remove `gateway` and `cron` from affected agent tool policies."}],"problemTypes":[{"descriptions":[{"lang":"en","description":"Improper Privilege Management","cweId":"CWE-269","type":"CWE"}]}],"affected":[{"vendor":"OpenClaw","product":"OpenClaw","defaultStatus":"unaffected","packageURL":"pkg:npm/openclaw","versions":[{"version":"0","status":"affected","versionType":"semver","lessThan":"2026.7.1"},{"version":"2026.7.1","status":"unaffected","versionType":"semver"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:openclaw:openclaw:*:*:*:*:*:*:*:*","versionEndExcluding":"2026.7.1"}]}]}],"metrics":[{"format":"CVSS","cvssV4_0":{"version":"4.0","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:L/SC:N/SI:N/SA:N","attackVector":"NETWORK","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"LOW","userInteraction":"NONE","vulnConfidentialityImpact":"LOW","vulnIntegrityImpact":"HIGH","vulnAvailabilityImpact":"LOW","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","baseScore":7.2,"baseSeverity":"HIGH"}},{"format":"CVSS","cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:L","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"HIGH","availabilityImpact":"LOW","baseScore":7.6,"baseSeverity":"HIGH"}}],"references":[{"url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-qw7m-h363-33qw","tags":["vendor-advisory"],"name":"GitHub Security Advisory (GHSA-qw7m-h363-33qw)"},{"name":"VulnCheck Advisory: OpenClaw before 2026.7.1 Authorization Bypass via chat.send","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/openclaw-before-2026.7.1-authorization-bypass-via-chat-send"}],"x_generator":{"engine":"vulncheck-endgame"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-28T19:32:56.856353Z","id":"CVE-2026-100578","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-28T19:34:23.662Z"}}]}}
