CVE-2026-45039 RustFS: Internode RPC HMAC secret falls back to public default credential, enabling peer impersonation

RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, the internode RPC layer authenticates every request with an HMAC-SHA256 signature using a shared secret. The function that produces this secret, getsharedsecret in crates/ecstore/src/rpc/httpauth.rs, falls back to...
