OpenClaw affected by denial of service through unguarded archive extraction allowing high expansion/resource abuse (ZIP/TAR)

Moderate severity GitHub Reviewed Published Feb 15, 2026 in openclaw/openclaw

Package

npm clawdbot (npm)

Affected versions

<= 2026.1.24-3

Patched versions

None
npm openclaw (npm)
< 2026.2.14
2026.2.14

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)

Release Process Note

This advisory will be updated with patched versions once the next npm release containing the fix is published.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
