要点
- CVE-2026-28452 は openclaw (openclaw), clawdbot, openclaw に影響する深刻度「中」 (CVSS 6.5) の脆弱性です。
- 今後30日間に悪用される確率（EPSS）：0.38%（全脆弱性の 32.0% より高い）。
- 対処：2026.2.14 以降に更新してください。
概要
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.

NVD の説明
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.
