CVE-2025-55131 high CVSS 7.1

Vulnerability in node-min (CVE-2025-55131)

Summary

Vulnerability in node-min (CVE-2025-55131). Confidential information can be exposed externally. Exploitable via Buffer.alloc. Mitigation: upgrade to 20.20.0, 22.22.0, 24.13.0, 25.3.0 or later.

Original description

The description as published by the source.

A flaw in Node.js's buffer allocation logic can expose uninitialized memory when allocations are interrupted, when using the vm module with the timeout option. Under specific timing conditions, buffers allocated with Buffer.alloc and other TypedArray instances like Uint8Array may contain leftover data from previous operations, allowing in-process secrets like tokens or passwords to leak or causing data corruption. While exploitation typically requires precise timing or in-process code execution, it can become remotely exploitable when untrusted input influences workload and timeouts, leading to potential confidentiality and integrity impact.

Update to 20.20.0, 22.22.0, 24.13.0, 25.3.0.

🛡️ Workaround

Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.

🔍 Detection

Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Run grep -r 'node-min' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify 
    grep -r 'node-min' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で node-min を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Apply patch patch 
    Upgrade node-min to 20.20.0, 22.22.0, 24.13.0, 25.3.0

    ステージング環境で 20.20.0, 22.22.0, 24.13.0, 25.3.0 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスを含めること。

  3. 3
    Post-deployment verification verify 
    Confirm patched version is live in production

    パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
