Trusted global runtime dotenv loading remains separate.\n\n## Fix Commit(s)\n- 0623079e98abf7202591f1b04a89755eb7ec9272\n\n## Verification\n- The fix commit is contained in the public v2026.4.22 tag.\n- openclaw@2026.4.22 is published on npm and the compiled package contains the fix.\n- Focused regression coverage for this path passed before publication.\n\nOpenClaw thanks @qi-scape for reporting.","published":"2026-05-11T16:46:41.355Z","modified":"2026-10-28T02:30:41.300711895Z","cvss":null,"epss":{"score":0.00105,"percentile":0.01182,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.4.22"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/0623079e98abf7202591f1b04a89755eb7ec9272","label":"openclaw/openclaw@0623079"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45003.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-55cf-xx38-4p9p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45003"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-connector-endpoint-host-override-via-workspace-dotenv-files"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/0623079e98abf7202591f1b04a89755eb7ec9272"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:41.300711895Z"}}
