CVE-2026-45041

A critical cryptographic vulnerability in RustFS distributed object storage allows complete license enforcement bypass. The application embeds a hardcoded 2048-bit RSA private key as a string constant (TEST_PRIVATE_KEY) in crates/appauth/src/token.rs, which is used in production via parse_license() to verify license tokens. Because this key is present in all published source releases and binaries, any par [truncated]

CVE-2026-45040

CVE-2026-45040 documents a sensitive information disclosure vulnerability in RustFS, a distributed object storage system implemented in Rust. When the server operates with RUST_LOG=debug, authentication credentials including SessionToken (JWT), SecretAccessKey, and complete JWT claims are emitted in plaintext to server logs. The vulnerability stems from improper logging practices that fail to sanitize sen [truncated]
