Pyroscope API Secret Key Leak via Tencent COS Backend <1.15.2/1.16.1/1.17.0
CVE-2025-41118 Published on April 15, 2026

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

Weakness Types

Incorrect Permission Assignment for Critical Resource

The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors. When a resource is given a permissions setting that provides access to a wider range of actors than required, it could lead to the exposure of sensitive information, or the modification of that resource by unintended parties. This is especially dangerous when the resource is related to program configuration, execution or sensitive user data.

Insertion of Sensitive Information Into Sent Data

The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor. Sensitive information could include data that is sensitive in and of itself (such as credentials or private messages), or otherwise useful in the further exploitation of the system (such as internal file system structure).
