+  "details": "## Vulnerability\n\n`skills/skill-creator/scripts/package_skill.py` (a local helper script used when authors package skills) previously followed symlinks while building `.skill` archives.\n\nIf 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.\n\n## Severity and Exposure\n\n- **Severity: Low**\n- **Execution context:** local/manual workflow only (skill author packaging step)\n- **No remote trigger:** this is not reachable via normal OpenClaw gateway/chat runtime paths\n- **No extraction Zip Slip in this finding:** this issue is limited to packaging-time symlink following\n\n## Impact\n\n- Potential unintentional disclosure of local files from the packaging machine into a generated `.skill` artifact.\n- Requires local execution of the packaging script on attacker-controlled skill contents.\n\n## Affected Components\n\n- `skills/skill-creator/scripts/package_skill.py`\n\n## Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Latest published version during triage: `2026.2.17`\n- Vulnerable version range: `<= 2026.2.17`\n- Planned patched version (next release): `2026.2.18`\n\n## Remediation\n\n- Reject symlinks during skill packaging.\n- Add regression tests for symlink file and symlink directory cases.\n- Update packaging guidance to document the symlink restriction.\n\n## Fix Commit(s)\n\n- `c275932aa4230fb7a8212fe1b9d2a18424874b3f`\n- `ee1d6427b544ccadd73e02b1630ea5c29ba9a9f0`\n\n## Related PR\n\n- https://github.com/openclaw/openclaw/pull/20796\n\n## Release Process Note\n\n`patched_versions` is pre-set to the planned next release (`2026.2.18`).
