Detailsinfo

A vulnerability has been found in RustFS up to 1.0.0-alpha.76 and classified as critical. Affected by this vulnerability is some unknown functionality of the component gRPC Authentication. The manipulation with an unknown input leads to a hard-coded credentials vulnerability. The CWE definition for the vulnerability is CWE-798. The product contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is known as CVE-2025-68926 since 12/25/2025. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1110.001 for this issue.

Upgrading to version 1.0.0-alpha.77 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2025-205801). If you want to get the best quality for vulnerability data then you always have to consider VulDB.
