{"id":"CVE-2026-28453","aliases":["GHSA-p25h-9q54-ffvw"],"url":"https://o3.security/vulnerability/CVE-2026-28453","summary":"OpenClaw < 2026.2.14 - Zip Slip Path Traversal in TAR Archive Extraction","details":"## Summary\nOpenClaw versions before 2026.2.14 did not sufficiently validate TAR archive entry paths during extraction. A crafted archive could use path traversal sequences (for example `../../...`) to write files outside the intended destination directory (Zip Slip).\n\n## Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Affected: `< 2026.2.14`\n- Fixed: `>= 2026.2.14`\n\n## Details\nThe affected code path is `extractArchive()` in `src/infra/archive.ts`. Prior to 2026.2.14, TAR extraction used `tar.x({ cwd: destDir })` without rejecting traversal and absolute entry paths.\n\nThis extraction is used by installation flows such as:\n- `openclaw plugins install …`\n- `openclaw hooks install …`\n\n## Impact\nIf a user installs an untrusted `.tar` / `.tgz` archive, an attacker can write files outside the extraction directory (within the permissions of the OpenClaw process). This can lead to configuration tampering and potentially code execution.\n\n## Mitigation\nUpgrade to `openclaw >= 2026.2.14`. Avoid installing untrusted plugin/hook archives.\n\n## Fix Commit(s)\n- `3aa94afcfd12104c683c9cad81faf434d0dadf87`\n\nOpenClaw thanks @xuemian168 for reporting.","published":"2026-03-05T21:59:31.079Z","modified":"2026-10-28T02:30:25.123053103Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.14"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/3aa94afcfd12104c683c9cad81faf434d0dadf87","label":"openclaw/openclaw@3aa94af"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28453.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-p25h-9q54-ffvw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-28453"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-zip-slip-path-traversal-in-tar-archive-extraction"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/3aa94afcfd12104c683c9cad81faf434d0dadf87"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:25.123053103Z"}}
