RSTUF Security Audit for 1.0.0
Author: Kairo de Araujo
Last update: 2025-03-24
We’re pleased to share the results of a recent security assessment of the Repository Service for TUF (RSTUF) services and tools, conducted by X41 D-Sec GmbH through the Open Source Technology Improvement Fund (OSTIF) and funded by the Open Source Security Foundation (OpenSSF).
This independent audit is part of the RSTUF roadmap and an important milestone toward releasing the first stable version, contributing to the open source supply chain ecosystem.
High-Level Summary
The assessment focused on the design, implementation, and deployment of RSTUF services and tools. The X41 team identified a set of findings ranging from low to high severity—importantly, no critical vulnerabilities were discovered.
Most findings relate to standard hardening practices and areas such as configuration, access controls, and deployment defaults. These insights are helping us improve the overall security and reliability of the RSTUF ecosystem.
All findings are tracked transparently in our public issue tracker: 🔍 Audit Findings - GitHub Issue #852
What’s Next
The RSTUF team has already begun addressing the findings and implementing the recommendations from the report. This includes improvements to security defaults, documentation, and deployment guidance.
Security is a continuous process, and this assessment is a valuable step in our ongoing efforts to deliver trusted and secure repository service for The Update Framework (TUF).
