### 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. ### Fix Commit(s) - `0dbb92dd2bcf9a32379d11c0f11ed016669dae3e` ### Related advisories - Canonical overlap (closed): GHSA-3pj7-x8jr-jvj8 - Duplicate variant (closed): GHSA-rgr7-g85h-6v82
