CVE-2026-45039

RustFS prior to 1.0.0-beta.2 uses an HMAC-SHA256 signature for internode RPC authentication that falls back to DEFAULT_SECRET_KEY = "rustfsadmin" if neither RUSTFS_RPC_SECRET nor the global S3 secret key is configured. The vulnerability arises from get_shared_secret() in crates/ecstore/src/rpc/ht...

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...

CVE-2026-45040

RustFS (Rust-based distributed object storage) prior to version 1.0.0-beta.2 leaks sensitive credentials in logs when RUST_LOG=debug, including SessionToken (JWT), SecretAccessKey, and full JWT claims. The issue’s impact is information disclosure in server logs. Mitigation is upgrading to 1.0.0-b...

CVE-2026-45041 RustFS: Hard-coded RSA private key in license verifier permits arbitrary license forgery

RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, crates/appauth/src/token.rs ships a 2048-bit RSA private key as a string constant named TESTPRIVATEKEY and uses it in production via parselicense to "verify" license tokens. Because the key is embedded in every...

CVE-2026-45041

CVE-2026-45041 affects RustFS prior to 1.0.0-beta.2, where crates/appauth/src/token.rs embeds a 2048-bit RSA private key (TEST_PRIVATE_KEY) as a string constant and uses it in production to verify licenses. This allows anyone who can read the source or extract the key from binaries to mint arbitr...
