Summary
OpenClaw: Reject symlinks in local skill packaging script
Details

Vulnerability

skills/skill-creator/scripts/package_skill.py (a local helper script used when authors package skills) previously followed symlinks while building .skill archives.

If an author runs this script on a crafted local skill directory containing symlinks to files outside the skill root, the resulting archive can include unintended file contents.

Severity and Exposure

  • Severity: Low
  • Execution context: local/manual workflow only (skill author packaging step)
  • No remote trigger: this is not reachable via normal OpenClaw gateway/chat runtime paths
  • No extraction Zip Slip in this finding: this issue is limited to packaging-time symlink following

Impact

  • Potential unintentional disclosure of local files from the packaging machine into a generated .skill artifact.
  • Requires local execution of the packaging script on attacker-controlled skill contents.

Affected Components

  • skills/skill-creator/scripts/package_skill.py

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published version during triage: 2026.2.17
  • Vulnerable version range: <= 2026.2.17
  • Planned patched version (next release): 2026.2.18

Remediation

  • Reject symlinks during skill packaging.
  • Add regression tests for symlink file and symlink directory cases.
  • Update packaging guidance to document the symlink restriction.
