{"cve":"CVE-2026-34426","nvd":{"published":"2026-04-02T19:21:31.727","modified":"2026-07-24T21:10:00.143","status":"Analyzed","description":"OpenClaw versions prior to commit b57b680 contain an approval bypass vulnerability due to inconsistent environment variable normalization between approval and execution paths, allowing attackers to inject attacker-controlled environment variables into execution without approval system validation. Attackers can exploit differing normalization logic to discard non-portable keys during approval processing while accepting them at execution time, bypassing operator review and potentially influencing runtime behavior including execution of attacker-controlled binaries.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N","score":7.3},"cwes":["CWE-184"],"references":["https://github.com/openclaw/openclaw/commit/b57b680c0c34de907d57f60c38fb358e82aef8f7","https://github.com/openclaw/openclaw/pull/59182","https://github.com/openclaw/openclaw/security/advisories/GHSA-98ch-45wp-ch47","https://www.vulncheck.com/advisories/openclaw-approval-bypass-via-environment-variable-normalization"],"products":["openclaw:openclaw"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-34426","score":0.0027,"percentile":0.19306,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-98ch-45wp-ch47","url":"https://osv.dev/vulnerability/GHSA-98ch-45wp-ch47","summary":"OpenClaw: Windows-compatible env override keys could bypass system.run approval binding","modified":"2026-07-08T08:11:38.347216822Z","packages":[{"ecosystem":"npm","name":"openclaw","purl":"pkg:npm/openclaw","ranges":["<2026.4.2"],"fixed":["2026.4.2"]}]},{"id":"GHSA-h3x4-hc5v-v2gm","url":"https://osv.dev/vulnerability/GHSA-h3x4-hc5v-v2gm","summary":"OpenClaw: Windows media loaders accepted remote-host file URLs before local path validation","modified":"2026-07-08T08:11:38.347216822Z","packages":[{"ecosystem":"npm","name":"openclaw","purl":"pkg:npm/openclaw","ranges":["<2026.3.22"],"fixed":["2026.3.22"]}]}],"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).
