Sensitive COS `SecretKey` exposed in plaintext via configuration API due to missing type protection

Summary

CVE	CVE-2025-41118
State	PUBLISHED
Assigner	GRAFANA
Source Priority	CVE Program / NVD first with legacy fallback
Published	2026-04-15 20:16:32 UTC
Updated	2026-07-20 12:16:59 UTC
Description	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.
