Description

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.

Affected Packages / Versions

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

Impact

Local DoS / availability impact when processing untrusted .tar.bz2 skill archives.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update openclaw to 2026.3.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-77hf-7fqf-f227 is resolved across your whole dependency graph.

  3. Workarounds

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
