After npm publish, maintainers only need to publish the advisory.\n\nOpenClaw thanks @zpbrent for reporting.","published":"2026-03-19T22:07:10.843Z","modified":"2026-08-17T03:48:14.316053311Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.26"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/258d615c45527ffda37cecd08cd268f97461bde0","label":"openclaw/openclaw@258d615"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32036.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-mwxv-35wr-4vvj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32036"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-authentication-bypass-via-encoded-dot-segment-traversal-in-api-channels"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/258d615c45527ffda37cecd08cd268f97461bde0"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-17T03:48:14.316053311Z"}}
