Executive Summary

Meteroid before version 2.2.0 has an authorization bypass flaw in the ApiTokensService GetApiTokenById gRPC handler. It fails to enforce the caller's tenant context, allowing authenticated users with settings:read permission to request another tenant's API token ID and retrieve its Argon2 secret hash and owning tenant ID.

Impact Analysis

An attacker with valid credentials and settings:read permission could access sensitive API token secrets of other tenants, potentially leading to unauthorized access to resources or data across tenant boundaries.

Compliance Impact

This vulnerability could violate data protection requirements by enabling unauthorized access to sensitive data across tenants, potentially breaching GDPR's principle of data minimization and HIPAA's access controls.

Mitigation Strategies

Upgrade Meteroid to version 2.2.0 or later to address the authorization bypass vulnerability in the ApiTokensService.
