A crafted skill name containing traversal segments (for example `../`) or an absolute path could cause the copy to write outside `<sandbox_workspace>/skills/`.\n\n## Impact\n\n- Files may be written outside the sandbox workspace root (within the permissions of the user running OpenClaw).\n\n## Attack Requirements\n\n- Attacker can provide a skill package (controls `SKILL.md` frontmatter).\n- Victim runs with sandbox enabled and skill mirroring into the sandbox workspace.\n\n## Affected Packages / Versions\n\n- `openclaw` (npm): `< 2026.2.14`\n\n## Fixed In\n\n- `openclaw` (npm): `>= 2026.2.14`\n\n## Fix Commit(s)\n\n- 3eb6a31b6fcf8268456988bfa8e3637d373438c2\n\nOpenClaw thanks @1seal for reporting.","published":"2026-03-05T21:59:34.867Z","modified":"2026-08-12T03:51:13.368521136Z","cvss":null,"epss":{"score":0.00132,"percentile":0.03017,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.14"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/3eb6a31b6fcf8268456988bfa8e3637d373438c2","label":"openclaw/openclaw@3eb6a31"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28457.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-xw4p-pw82-hqr7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-28457"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-path-traversal-in-sandbox-skill-mirroring-via-name-parameter"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/3eb6a31b6fcf8268456988bfa8e3637d373438c2"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:13.368521136Z"}}
