EPSS · scored 2026-10-27

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.

Vendor and ecosystem advisories describing this.

  • WID-SEC-W-2026-0424OpenClaw: Mehrere SchwachstellenDeutsch2026-02-15csaf · cert_bundDE

    Ein Angreifer kann diese Schwachstellen in OpenClaw ausnutzen, um beliebigen Programmcode auszuführen, sich erhöhte Berechtigungen zu verschaffen, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren, einen Denial-of-Service-Zustand herbeizuführen, vertrauliche Informationen offenzulegen oder andere, nicht näher bezeichnete Angriffe durchzuführen.

  • GHSA-h89v-j3x9-8wqjOpenClaw affected by denial of service through unguarded archive extraction allowing high expansion/resource abuse (ZIP/TAR)2026-02-18ghsa · osvUS

    ## 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.
