OpenObserve: Unauthenticated /config/runtime endpoint exposes PostgreSQL database credentials
OpenObserve is a cloud-native observability platform. Prior to 0.90.3, OpenObserve registers the /config/runtime endpoint without authentication and serializes the complete server configuration after applying the hide_sensitive_fields keyword filter. The filter does not recognize dsn or creds field names, so meta_postgres_dsn, meta_postgres_ro_dsn, meta_ddl_dsn, and usage_reporting_creds can be returned in plaintext to an unauthenticated network client. PostgreSQL deployments can expose database credentials, and the same response can disclose the root administrator email address, internal NATS address, filesystem layout, and other deployment details. This issue is fixed in version 0.90.3.
