CVE-2025-41118 critical CVSS 9.1

Vulnerability in github.com/grafana/pyroscope (CVE-2025-41118)

Summary

Vulnerability in github.com/grafana/pyroscope (CVE-2025-41118). Confidential information can be exposed externally. Mitigation: upgrade to 1.15.2, 1.16.1 or later.

Original description

The description as published by the source.

Pyroscope is an open-source continuous profiling database. The database supports various storage backends, including Tencent Cloud Object Storage (COS).

If the database is configured to use Tencent COS as the storage backend, an attacker could extract the secret_key configuration value from the Pyroscope API.

To exploit this vulnerability, an attacker needs direct access to the Pyroscope API. We highly recommend limiting the public internet exposure of all our databases, such that they are only accessible by trusted users or internal systems.

This vulnerability is fixed in versions:

1.15.x: 1.15.2 and above.
1.16.x: 1.16.1 and above.
1.17.x: 1.17.0 and above (i.e. all versions).

Thanks to Théo Cusnir for reporting this vulnerability to us via our bug bounty program.

❓ What is the problem

A vulnerability (CWE-732) exists in github.com/grafana/pyroscope.

📍 Affected scope

Check the vendor advisory for the affected versions of github.com/grafana/pyroscope.

🔥 Severity

Severity: Critical (CVSS 9.1/10). Confidential information can be exposed externally.

🔧 How to fix

Update to 1.15.2, 1.16.1.

🛡️ 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 'github.com/grafana/pyroscope' . 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 'github.com/grafana/pyroscope' . | 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 github.com/grafana/pyroscope 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 github.com/grafana/pyroscope to 1.15.2, 1.16.1

    ステージング環境で 1.15.2, 1.16.1 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。
