Vulnerability from github – Published: 2026-02-18 00:52 – Updated: 2026-03-06 00:58

Summary

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

Details

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.

Release Process Note

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

CVE-2026-28452 (GCVE-0-2026-28452)

Vulnerability from cvelistv5 – Published: 2026-03-05 21:59 – Updated: 2026-03-09 16:55

Title

OpenClaw < 2026.2.14 - Denial of Service via Unguarded Archive Extraction in extractArchive

Summary

OpenClaw versions prior to 2026.2.14 contain a denial of service vulnerability in the extractArchive function within src/infra/archive.ts that allows attackers to consume excessive CPU, memory, and disk resources through high-expansion ZIP and TAR archives. Remote attackers can trigger resource exhaustion by providing maliciously crafted archive files during install or update operations, causing service degradation or system unavailability.
