{"id":"GHSA-6fvr-66p3-3qj4","summary":"OpenClaw: Hook-triggered CLI runs could receive owner MCP tool authority","details":"### Summary\n\nOpenClaw hook ingress can start automated agent runs using a configured hook token. In affected releases, a hook-triggered run could select a bundled CLI backend that received owner-scoped MCP loopback authority instead of a scope appropriate for hook ingress.\n\nThis issue affects the boundary between hook-token automation and owner-only MCP tools. It does not affect deployments with hooks disabled.\n\n### Affected configurations\n\nThis affects deployments where hooks are enabled, `/hooks/agent` is reachable with a valid hook token, and a bundled CLI backend can be selected for the hook-triggered run.\n\n### Impact\n\nA caller with the hook token could cause the spawned CLI runtime to see or call MCP tools that should have been owner-only. The practical impact depends on which MCP tools are available; the reported proof used persistent cron state as a representative owner-only action.\n\n### Patched Versions\n\nThe first stable patched version is `2026.5.20`.\n\nFixed in the `2026.5.20` stable release.\n\n### Mitigations\n\nUpgrade to `openclaw@2026.5.20` or later. Keep hook tokens secret, restrict network access to hook endpoints, and disable hooks when they are not needed.","aliases":["CVE-2026-53814"],"modified":"2026-07-02T16:26:33.194781Z","published":"2026-07-02T16:05:03Z","database_specific":{"cwe_ids":["CWE-200","CWE-266","CWE-284"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-07-02T16:05:03Z","nvd_published_at":"2026-06-11T21:16:23Z"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-6fvr-66p3-3qj4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53814"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-privilege-escalation-via-hook-triggered-cli-mcp-tool-authority"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.5.20"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-6fvr-66p3-3qj4/GHSA-6fvr-66p3-3qj4.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:L"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N"}]}
