Unauthorized callers may access plugin channel APIs that are expected to require gateway auth.\n\nCWE: CWE-288 (Authentication Bypass Using an Alternate Path or Channel)\nCVSS: `CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N` (Base 5.3, Moderate)","published":"2026-03-19T22:07:07.094Z","modified":"2026-08-17T03:55:01.674279087Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.26"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32031.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-8j2w-6fmm-m587"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32031"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-authentication-bypass-via-path-canonicalization-mismatch-in-api-channels-gateway"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-17T03:55:01.674279087Z"}}
