Summary

A local helper script in OpenClaw, `skills/skill-creator/scripts/package_skill.py`, followed symlinks while building `.skill` archives. When an author runs it on a crafted skill directory containing symlinks to files outside the skill root, the archive can include unintended file contents. The issue affects `openclaw` (npm) versions `<= 2026.2.17` and is rated Low severity, since it requires local execution and is not reachable through the gateway or chat runtime.

Mitigation

Reject symlinks during skill packaging, add regression tests for symlink file and symlink directory cases, and update packaging guidance to document the symlink restriction. The planned patched version is 2026.2.18.
