Summary
OpenClaw skills-install-download: tar.bz2 extraction bypassed archive safety parity checks (local DoS)
Details

Summary

The tar.bz2 installer path in src/agents/skills-install-download.ts used shell tar preflight/extract logic that did not share the same hardening guarantees as the centralized archive extractor.

This allowed crafted .tar.bz2 archives to bypass special-entry blocking and extracted-size guardrails enforced on other archive paths, causing local availability impact during skill install.

  • Package: openclaw (npm)
  • Latest published at triage time: 2026.3.1
  • Affected range: <= 2026.3.1
  • Patched in: 2026.3.2 (released)

Impact
