CVE-2026-28453

OpenClaw < 2026.2.14 - Zip Slip Path Traversal in TAR Archive Extraction

8.3 HighFix available

OpenClaw versions prior to 2026.2.14 fail to validate TAR archive entry paths during extraction, allowing path traversal sequences to write files outside the intended directory. Attackers can craft malicious archives with traversal sequences like ../../ to write files outside extraction boundaries, potentially enabling configuration tampering and code execution.

OpenClaw has Zip Slip path traversal in tar archive extraction

Summary

OpenClaw 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).

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected: < 2026.2.14
  • Fixed: >= 2026.2.14

Details

The 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.

This extraction is used by installation flows such as:

  • openclaw plugins install …
  • openclaw hooks install …

Impact

If 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.

Mitigation

Upgrade to openclaw >= 2026.2.14. Avoid installing untrusted plugin/hook archives.
