Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-68926 affects RustFS, a distributed object storage system. Prior to version 1.0.0-alpha.77, RustFS uses a hardcoded static token, "rustfs rpc", for gRPC authentication. This token is exposed in the source code repository and is the same on both the client and server sides. The hardcoded token is non-configurable, lacks a rotation mechanism, and is universally valid across all RustFS deployments. An attacker with network access to the gRPC port can use this publicly known token to authenticate and perform privileged operations, including data destruction, policy manipulation, and cluster configuration changes. Version 1.0.0-alpha.77 addresses this vulnerability.

Description: RustFS is a distributed object storage system built in Rust. In versions prior to 1.0.0-alpha.78, RustFS implements gRPC authentication using a hardcoded static token `"rustfs rpc"` that is publicly exposed in the source code repository, hardcoded on both client and server sides, non-configurable with no mechanism for token rotation, and universally valid across all RustFS deployments. Any attacker with network access to the gRPC port can authenticate using this publicly known token and execute privileged operations including data destruction, policy manipulation, and cluster configuration changes. Version 1.0.0-alpha.78 contains a fix for the issue.
