CVE-2025-41118: Vulnerability in Grafana Pyroscope
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.
AI Analysis
Technical Summary
Pyroscope versions configured with Tencent COS as the storage backend expose the secret_key configuration via the Pyroscope API if accessed by an attacker. This vulnerability requires direct API access and allows extraction of sensitive secret_key credentials. The issue is fixed in Pyroscope versions 1.15.2 and above for 1.15.x, 1.16.1 and above for 1.16.x, and all 1.17.x versions. The CVSS 3.1 score of 9.1 reflects network attack vector, low complexity, no privileges or user interaction required, and high confidentiality and integrity impact.
Potential Impact
An attacker with direct access to the Pyroscope API can extract the secret_key used for Tencent COS storage backend, leading to unauthorized disclosure of sensitive credentials. This compromises confidentiality and integrity of the system configuration. There is no indication of availability impact. No known exploits in the wild have been reported.
Mitigation Recommendations
This vulnerability is fixed in Pyroscope versions 1.15.2 and above (1.15.x), 1.16.1 and above (1.16.x), and all 1.17.x versions. Users should upgrade to these fixed versions to remediate the issue. Additionally, it is strongly recommended to limit public internet exposure of the Pyroscope API to trusted users or internal systems only, reducing the risk of unauthorized access.
