Summary

Apollo is a reliable configuration management system suitable for microservice configuration management scenarios. Prior to 2.5.2, Apollo ConfigService may allow unauthorized access to raw configuration data when AccessKey or management key authentication is enabled because requests under /configfiles/raw/{appId}/{clusterName}/{namespace} are parsed for authentication as appId raw instead of the actual path appId, causing ConfigService to look up AccessKey secrets for raw before verifying the request signature and potentially continue without signature verification for the target appId. This issue is fixed in version 2.5.2.
