CVE-2026-27607 (opens in a new tab)Amendment
This was deemed not a vulnerability.
Overview
rustfs is a high-performance distributed object storage software built using Rust, one of the most popular languages worldwide. Along with MinIO, it shares a range of advantages such as simplicity, S3 compatibility, open-source nature, support for data lakes, AI, and big data. Furthermore, it has a better and more user-friendly open-source license in comparison to other storage systems, being constructed under the Apache license.
Affected versions of this package are vulnerable to Incorrect Authorization in the presigned PostObject uploads. An attacker can upload files that exceed size limits, use arbitrary object keys, and spoof content types by bypassing policy conditions such as content-length-range, starts-with, and Content-Type constraints.
