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.","published":"2026-04-02T18:25:14.022Z","modified":"2026-08-09T03:30:15.021065766Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.4.2"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/b57b680c0c34de907d57f60c38fb358e82aef8f7","label":"openclaw/openclaw@b57b680"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34426.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-98ch-45wp-ch47"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34426"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-approval-bypass-via-environment-variable-normalization"},{"type":"REPORT","url":"https://github.com/openclaw/openclaw/pull/59182"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/b57b680c0c34de907d57f60c38fb358e82aef8f7"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-09T03:30:15.021065766Z"}}
