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.
