Affected packages

• npm openclaw: < 2026.2.14 → fixed in 2026.2.14 • npm clawdbot: <= 2026.1.24-3 (no fix yet)

Description

Summary Archive extraction lacked strict resource budgets, allowing high-expansion ZIP/TAR archives to consume excessive CPU/memory/disk during install/update flows. Affected Packages / Versions • openclaw (npm): <= 2026.2.13 • clawdbot (npm): <= 2026.1.24-3 Details Affected component: `src/infra/archive.ts` (`extractArchive`). The extractor now enforces resource budgets (entry count and extracted byte limits; ZIP also enforces a compressed archive size limit) and rejects over-budget archives. Fix Commit(s) • openclaw/openclaw@d3ee5deb87ee2ad0ab83c92c365611165423cb71 • openclaw/openclaw@5f4b29145c236d124524c2c9af0f8acd048fbdea Release Process Note This advisory will be updated with patched versions once the next npm release containing the fix is published.
