Summary
OpenClaw has Zip Slip path traversal in tar archive extraction
Details

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.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
