Description

RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, RustFS suffers from sensitive information leakage in log outputs. When the server is run with RUST_LOG=debug sensitive credentials including SessionToken (JWT), SecretAccessKey, and full JWT claims are printed in plaintext to the server logs. This vulnerability is fixed in 1.0.0-beta.2.
