What it is

RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, the RustFS console endpoint GET /rustfs/console/license returns parsed license metadata without requiring authentication. The endpoint is registered on the console listener and returns JSON containing license information such as the license subject and expiration timestamp. Any client that can reach the console listener can query this endpoint without credentials. This vulnerability is fixed in 1.0.0-beta.2.
