To report a security vulnerability in apache/spark-connect-rust, follow the ASF security process at https://www.apache.org/security/. Reports can be sent privately to security@apache.org or to private@spark.apache.org.
This repository implements the Rust client for the Spark Connect RPC protocol. Apache Spark's security guidance for operators is documented at:
https://spark.apache.org/docs/latest/security.html
That document covers authentication, encryption, access control, Kerberos integration, trust boundaries, environmental assumptions, security properties provided and not provided, and downstream operator responsibilities. The client-side trust assumptions for Spark Connect (RPC channel, credential material, TLS validation) inherit from that model.
Automated security scanning agents should consult that document for the project's in-scope / out-of-scope declarations before reporting issues.
