CVE-2026-47136: RustFS: Unauthenticated RustFS console license endpoint exposes license metadata
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.
