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.
