Summary
OpenClaw: ZIP extraction race could write outside destination via parent symlink rebind
Details

Summary

ZIP extraction in OpenClaw could be raced into writing outside the intended destination directory via parent-directory symlink rebind between validation and write.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Vulnerable versions: <= 2026.3.1
  • Latest published vulnerable version confirmed: 2026.3.1 (npm as of 2026-03-02)
  • Patched version: 2026.3.2 (released)

Technical Details

In src/infra/archive.ts, ZIP extraction previously validated output paths, then later opened/truncated the destination path in a separate step. A local race on parent-directory symlink state could redirect the final write outside the extraction root.

The fix hardens ZIP writes by binding writes to the opened file handle identity and avoiding the pre-write truncate race path, with shared fd realpath verification in src/infra/fs-safe.ts and regression coverage in src/infra/archive.test.ts.
