Attackers with a valid hook token can exploit the /hooks/agent endpoint to cause spawned CLI runtimes to access or invoke owner-only MCP tools, potentially executing privileged actions like persistent cron state modifications.","cvss_v4":{"vector":"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","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L","score":8.3},"cwes":["CWE-266"],"references":["https://github.com/openclaw/openclaw/security/advisories/GHSA-6fvr-66p3-3qj4","https://www.vulncheck.com/advisories/openclaw-privilege-escalation-via-hook-triggered-cli-mcp-tool-authority"],"products":["openclaw:openclaw"],"source":"nvd","synced_at":"2026-10-19T22:38:48.522727527+00:00"},"epss":{"cve":"CVE-2026-53814","score":0.00281,"percentile":0.20646,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-6fvr-66p3-3qj4","url":"https://osv.dev/vulnerability/GHSA-6fvr-66p3-3qj4","summary":"OpenClaw: Hook-triggered CLI runs could receive owner MCP tool authority","modified":"2026-07-02T16:26:33.194781Z","packages":[{"ecosystem":"npm","name":"openclaw","purl":"pkg:npm/openclaw","ranges":["<2026.5.20"],"fixed":["2026.5.20"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
