Description
Summary
A path confinement bypass in OpenClaw ZIP extraction allowed writes outside the intended destination when a pre-existing symlink was present under the extraction root.
Affected Packages / Versions
- Package:
openclaw(npm) - Latest published npm version at triage time:
2026.2.21-2 - Affected versions:
<= 2026.2.21-2 - Planned patched version for next release:
2026.2.22
Technical Details
The vulnerable path was in src/infra/archive.ts ZIP extraction logic. Output-path checks were lexical, but writes could still traverse an existing symlink in destination path segments.
The fix blocks this by:
- rejecting symlink traversal in destination path segments,
- validating resolved destination paths remain inside the extraction root,
- using no-follow file opens for ZIP output writes where supported,
- adding a regression test for pre-seeded destination symlink traversal.
Impact
- Type: Arbitrary file write outside extraction root via symlink traversal during ZIP extraction.
- Preconditions: attacker-controlled archive extraction plus pre-existing symlink in destination path.
Fix Commit(s)
- 4b226b74f5fd3b106a83a6347fd404172e2fd246
Release Process Note
Patched version is pre-set to the planned next release (2026.2.22).
Once npm release 2026.2.22 is published, the advisory can be published without further field edits.
OpenClaw thanks @tdjackey for reporting.
