openclawnpmclawdbotnpmDescription
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.

Open-source dependencyDetect
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.
Fix
Update openclaw to 2026.2.14 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h89v-j3x9-8wqj is resolved across your whole dependency graph.
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.
