Aliases CVE-2026-28452
Summary OpenClaw affected by denial of service through unguarded archive extraction allowing high expansion/resource abuse (ZIP/TAR) ## 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. ## Credits Thanks @vincentkoc for reporting.
